Is an Google product that allows you to make simple visualizations using an online tool, democratizing the process of visualization design. It's possible to interact with Javascript via Visualizations made with Flare or Prefuse won't easily work on mobile devices, and are hard to integrate into other web components. Unfortunately Flash and Java applets are rapidly becoming (or already are) out of date. The Flare library hasn't been updated since January 2009 - not that there's major bugs or anything, but it hasn't seen the latest and greatest (Flare Assistance Pool) which has a lot of sample code and explains many common pitfalls. Many useful abstractions like DataSets, filters, and property encoders allow you to easily manipulate a data set once it's loaded.ĭocumentation and examples are a bit lacking: Definitely check out Animated transitions between layouts are also possible with theĬlass, which interpolates properties for you automatically. These are very full-featured libraries that can be adapted to a variety of projects.īy using the object-oriented languages of Java and ActionScript 3, it's quite easy to modify components of the libraries - replacing how lines are rendered or how groups are calculated in a visualization is as hard as dropping a single file in the right place.ĭemos, there are a plethora of layouts and chart types you can choose from. Here are five of my favorites, in increasing order of my preference.įlare, were the first visualization frameworks that I used extensively. ![]() While no framework can address all needs, over the years I've had the chance to experiment with many of the popular ones and learn their strengths and weaknesses. People often ask me to explain what tools I use to make visualizations and interactive projects. It's nice to write something like:Īnd see a circle, where you can immediately start tweaking the parameters, explore other drawing functions, and ask questions like "how can I change the color?" Compare this to the typical introductory programming lesson: Coding visualizations is a great way to learn programming because it's inherently rewarding.
