Data Driven Documents, or D3. Or to put it more simply, D3. It was developed by Mike Bostock with the idea of bridging the gap between static display of data, and interactive and animated data visualizations. D3 is a powerful library with a ton of uses. All the data transformations and renderings are done client-side, in the browser. At its simplest, D3. Here is a simple example where D3. The strength of D3. For example, it can be used to create charts.
It can be used to create animated charts. It can be even used to integrate and animate different connected charts. But D3. Manipulating and presenting geographic data can be very tricky, but building a map with a D3.
Here is a D3. Map styling is done via CSS.
For this D3. TopoJSON eliminates redundancy by storing relational information between geographic features, not merely spatial information. As a result, geometry is much more compact and combined where geometries share features. So, for example, given a map with several countries bordering each other, the shared parts of the borders will be stored twice in GeoJSON, once for each country on either side of the border. Today, the most popular mapping libraries are Google Maps and Leaflet.
Leaflet is at its best when leveraging the big selection of raster-based maps that are available around the internet, and brings the simplicity of working with tiled maps and their presentation capabilities. Leaflet can be used with great success when combined with D3. Combining them together brings out the best in both libraries.SVG or Scalable Vector Graphics is an XML-based file format that enables developers and designers to create high quality, dynamic graphics and graphical applications with a great level of precision.
All modern browsers support rendering SVG: however, for older browsers like IE6, 7 and 8 without native support, you can fall back on polyfills such as SVG Web that use Flash for rendering content.
This enables you to easily target the majority of users online without worrying about compatibility issues. For mobile web developers wondering about compatibility, I'm happy to report that iOS 3. The answer to this concern is actually both. Canvas offers a high-performance canvas best suited to rendering raster graphics for games such as sprites, image editing and applications that require per-pixel manipulation capabilities.
Unfortunately, the performance of canvas apps degrades as resolutions increase and wouldn't be recommended for use in full-screen user interfaces. SVG is resolution-independent, making it ideal for rendering cross-platform user interface components, animations and applications where each element needs to be accessible via the DOM.
We're going to take a look at 20 excellent examples of SVG use out in the wild, so fire up a modern browser and check out the demos below. A big reason designers and developers initially flocked to using Flash was its ease of creating immersive, animated user experiences with a respectable frame rate.
A great example of SVG in action - not bad for something that doesn't require third-party plug-ins! One of the true tests for comparing existing approaches to achieving a task to new ones is evaluating just how far you can take replicating an example of what's already out there.
That's just what Marek Raida did when he saw a Flash banner of several world landmarks animating in the corner of a page and decided to try recreating it in SVG. The result of his efforts is a lightweight demo that clocks in at a filesize 33 per cent smaller than its Flash alternative. This example of SVG manages to look much better and isn't that hard to code up yourself either! Whilst SVG offers a great deal of power in the vector-graphics space, it also has a number of creative uses outside of it.
The blur effect is possibly the most interesting but other effects such as inversing the frame content are also quite interesting proofs of concept. Whenever the topic of in-browser graphics rendering is discussed it's impossible to avoid talking about the level of 2D and 3D capabilities that are available.
The impact on online gaming that this presents is enough to spark plenty of designers and developers to pay attention, so how can SVG help us with this? Be sure to check out the drop-down on the page as there are plenty of examples available to whet your 3D appetite.
Using the library and including native SVG support you can instantly target almost 95 per cent of the existing installed web base, which is quite considerable if you want to consider using SVG in production. The great thing about this example is that it allows you to compare how vector graphics may look when rendered using SVG as opposed to Flash, but this can be easily switched at runtime depending on the level of support your browser has for it.
Definitely a must-see for developers interested in exploring SVG's rendering capabilities further. Back when Flash first came out, some of the first examples we saw of it in the wild were of basic puzzles and games. It'll give you a selection of images and let you generate a puzzle out of any you select. Tricky to complete, but fun and some interesting code behind it none the less!
As mentioned in the introduction, one area where Flash has been heavily utilised in the past that SVG also excels on is creative vector-based user interfaces.
Tutorial - Creating an Interactive SVG map
With screens and screen resolutions constantly increasing in size, it's necessary for developers to be able to cater for high-quality UI components without the worry of quality suffering at a higher or lower resolution.
This is where SVG comes in particularly useful. In this great example of SVGan interactive subtitle bar is attached to a HTML5 video player, allowing you to easily switch between subtitle languages seamlessly.
A few years ago, I remember working on a project where we had to apply a mask around embedded Flash video, so it appeared that the video was playing right inside a block shaped like text.Most recently, I was tasked with creating a masterplan architectural, not the evil villain kind for Little Kelhama property development at Kelham Island in Sheffield built by Citu.
They needed two versions of the masterplan: a map to highlight the residential properties they have available, and a map for their commercial properties. SVG is supported in most browsers except IE8 and below. It currently supports Firefox 3.

A Map to Perfection: Using D3.js to Make Beautiful Web Maps
The use of this particular kind of visual navigation has declined in recent years due, in part, to the fact that the 'hotspot' interface areas of image maps were defined in pixels. This made them both difficult and tedious to build, while the result of this process was non-responsive: if the image in the image map is resized, the associated hyperlinks drift out of registration with the underlying visual elements, making navigation a case of hunting, clicking and luck.
This makes traditional image maps inappropriate for modern mobile website design, yet they remain a valuable user interface pattern, especially for interactive diagrams and geographical locations.
With a little cleverness, we can use the power of SVG to improve upon the image map, while eliminating the drawbacks of the traditional version. SVG doesn't suffer from a registration issue because the format has its own internal viewport system. So long as the file is set up correctly, bitmap images and polygon points in an SVG document will scale and move relative to each other, preserving the integrity of navigational linked hotspots. At the same time, SVG is a vector format that will remain 'perfect' no matter what size it's scaled to.
We can also combine the features of SVG and CSS3 to create powerful transition effects in the reborn image map, which is something that was impossible to do in the traditional version. To illustrate this, we'll use a geographical map as the basis for our image map. For this example, I'll use a map of my adopted country of Canada, simplified down to the western provinces for the sake of clarity.
Generally speaking, complex modifications to an SVG file are best left to a vector illustration tool, which can manipulate the file graphically.
Today, most such tools support the SVG format. Exported from Illustratorthe code of the SVG file will look something like this:. It's straightforward to clean up the code: remove comments, prolog, doctype as well as any attributes we don't need. That turns the code into this:.
After linking each path, look at the SVG file in a browser: the exact outline of the Alberta province becomes the hotspot area of the associated link, and scales with the document and viewport window. There are several ways to integrate interactive SVG into a web page: as an object, an iframe, or with the code added directly into the page.
We'll use the latter. Copy and paste the edited SVG code like so:. Currently, the SVG document takes up the entire space of the viewport, and the paths are filled with black. Let's change that while adding to the interactivity of the linked areas.
In the host HTML document's embedded style, or in a stylesheet linked to the document, add the following:. We can cure that by making the SVG responsive. Right now, the SVG map works as a simple image map with hover effects. The vector points of the paths automatically create hotspots on the map, saving a great deal of development time, and they scale with the browser window, making the map responsive. SVG is automatically alpha-masked, so we can include any content behind the image map without interfering with the map's graphical quality.
We can enhance the visuals of the map by adding clipped photographs inside each map area that will fade in during mouseover. It's probably easiest to Place the images in Illustrator, although you can achieve the same result by hand coding: simply scale and position the photographs in front of the appropriate province, making sure that each image covers its province completely.
After exporting the result, repeat the clean-up operation and:. Before applying the clip-path attribute on the images you may find it necessary to manually readjust the position of each image to get it in the right location by changing its x and y value together with its height and widthafter removing the transform attribute that Illustrator applies.
The current SVG spec doesn't have strong support for accessibility, but we can improve things by adding appropriate titleaccesskey and ARIA role attributes:.
For a format that is intended to be infinitely scalable, it's ironic that the task of making SVG responsive on a web page can be quite challenging.
If you're adding an SVG image to a page as an inline image, it can be made responsive in exactly the same way as you would a bitmap:. However, we can't use this approach for the image map used in this tutorial as inline SVG images will not support interactivity. Instead, we must embed the SVG code directly on the page.
With the cleaned-up code I suggest in the article, the embedded image map will be responsive, but at the cost of a large vertical gap appearing above and below the illustration.Here's the GitHub Repo for you to clone. Making an interactive and responsive map is much easier than you would think. The goal is to make it so that hovering over a state will display the name of the state, along with its capital.
Additionally, it will be able to adapt to any screen size. By the end of this tutorial you'll be able to do this using any map you'd like. This is useful if you want to show interactive maps of the world, countries, or states.
An excellent application of this is CNN's interactive primaries map. You would normally start by searching on Google for a map of the United States in.
For the sake of this tutorial, let's use the one from Wikipedia. A lot of people don't know this, but SVG files can be opened using any text editor. Do this and paste it into your favorite text editor. Notice how there are a bunch of path tags with ids? Each path in the code corresponds to a state. You'll see that only Florida is orange. The other states have the color D3D3D3 because that's what it's set to in the xml code. Now delete the orange fill and go back to the SVG code.
If you change the viewport size, you'll notice that the map is not responsive. In order to fix that simply add the following code to your CSS file. Now if you shrink the viewport, the SVG is responsive. The problem is that the map isn't aligned at the top.
This forces the map to stay at the top when shrinking the viewport. Next we want to make it so that hovering over a state causes it to change colors let's use which is Old Glory Blue from the US flag. We'll take advantage of CSS hover to accomplish this. The cursor should be a pointer, and the outline stroke will also be blue.
It's time to display the state name and capital on hover. This box will show state name and capital. Let's style it by using the code below. To complete the trifecta of American flag colors, we'll use white for the background color. The z-index needs to be set to 1 to make the box appear in front of the map.
We set display to none so that the box is not visible unless a state is hovered. We're almost done. Repeat this for all of the states. You can now intuitively add extra information in order to customize this even more. The final step is to add the following jQuery code so that hovering shows the information box with state name and capital.Tutoriel jQuery : Créer une carte interactive
The selector for path selects a state. The circle represents Washington DC. As you can see in the code, hovering over path or circle causes the info box to become visible. Moving the mouse away from the map causes the info box to disappear.
The mousemove method makes the info box appear above the mouse. That's all of the code!Photos are now available on Vecteezy! Prev 1 Next of Vector World Map. Vector Grey World Map. Worldmap Silhouette Free Vector. Grayscale Vector Worldmap. World Map Vector Background. World map silhouette.
