These are the best open-source chart libraries for data visualization
When you’re building a data visualization, the last thing you want to do is spend time on the wrong tool. You need something that’s easy to use, feature-rich and open source–and most importantly, well documented.
- Easy-to-use interface: A good UI makes both data exploration and creation much easier than using non-interactive tools like Photoshop or Illustrator. It should also provide plenty of options for customization (if needed).
- Feature-rich: A useful chart library should be packed with features such as interactive navigation bars etc., but don’t worry if some of these features aren’t available today; they will come soon enough!
