Take the new social network visual below by Zoom Charts. When you click on the face, a donut graph displays social network usage stats in the hover over. You can even drill down on any of the donut parts creating another donut outside of the first one.
Tell me what you think – have you found a way to enhance donut and funnel charts to make them more effective in displaying data?
Also, feel free to send me a chart that you’re grappling with and I’d be happy to provide you with input on how to improve it. Just email me at firstname.lastname@example.org.
