Saw this linked to on Daring Fireball. I’m not ready to use it today but might in the future.
Simple question: are you building custom charts? Victory is used by companies like Airbnb, FiveThirtyEight, and speedtest.net. Victory makes it easy to get started without sacrificing flexibility. Use the same API to create charts for web and mobile devices. And the results are gorgeous. Seriously, even if youre not a web developer, you should go check out their website and see how beautiful these charts are. And not in a show-y off-y bullshit way like using 3D for two-dimensional data. No Victory lets you easily create charts that are gorgeous in the sense of traditional graphic design and serious data visualization practices. The documentation is alive you can play with the charts just by clicking and dragging.
Victory is created and supported by the open source team at Formidable, free use under the MIT license. There is no catch here. Its an open source library that you can just use.
