Depending on the Open Source Sphere
In this chapter we will cover:
Animating a gauge meter (jqPlot)
Creating an animated 3D chart (canvas3DGraph)
Charting over time (flotJS)
Building a clock with RaphaelJS
Making a sunburst chart with InfoVis

The open source data visualization community is extremely rich and detailed with many options and some really amazing libraries. Each library has its strong points and its disadvantages. Some are standalone codes while other depend on other platforms such as Jquery. Some are really big, and some are really small—there isn't one option that is perfect for all opportunities, but with such a rich amount of options the most important thing is to figure out what library is the right one for you.
There is always a given way when working with open source libraries, mainly when it comes to file sizes and having just too much features that drag down the speed of your application, load time, and so on. But with the richness and creativeness of the community, it's hard to avoid really fantastic charts that can be created in minutes instead of hours.
In this chapter we will explore working with some of these options. Instead of using the libraries according to the documentation of the projects, our goal will be to find ways to override the built-in libraries to enable us a better control over our applications in case we can't find a suitable solution in the documentation of an application. So, the goal in this chapter is now doubled—to find ways to do things that aren't naturally set to work and to find ways to bypass problems.
One more important thing to note is that all of these open source libraries have copy rights. It is advised that you check the legal documentation of the project before you go ahead with it.
