Below is a more basic file for the Ring Chart. What is tricky about the ring chart is that each data series has its own objects you need to create – as seen in the createSeries() functions. This is demonstrated in the RingChart docs as well – but it doesn’t go too in depth. Anyway – here is the code for the basic example. It still relies on an external data file because there are so many time series data points. If you put this in the directory as the RingChart test container it should work just fine.

-thank you! So awesome! -I noticed that the example HTML page defaulted to the ‘Climate’ theme. Do you happen to have the same HTML example with the “Ghost” theme? If not, I could try to target each and every part of the ghost theme and update it under .style… but I’m super hopeful you have something consolidated!

Thanks so so so much!

Hello Deasus,

So the themes are a bit more involved, they are combination of styles and functions. I encourage you to take a deeper look at the demo/RingChartDemo.js file. But I have put them all together in a single file here. Vizuly is designed to be a highly customizable visualization library – but it does come with a certain level of complexity for these more advanced techniques.

The Ring Chart is by far the most complex Vizuly component – most component themes are just a collection of style settings, but here you go with all the code in one file.
