Tim Hurson just found this site that creates beautiful visualizations of data. Check out this chart, comparing returning Mindcampers to first-timers. Be sure to run your mouse over the chart to see the magic!
You can find the (free!) browser-based open-source software at Datawrapper (www.datawrapper.de/). Thanks, Tim!
