Sam’s highcharts looks good. Photoshop is too expensive for most with an occasional need for charting. I ended up using http://www.onlinecharttool.com/ . When you start out, you have to choose a chart type then scroll down, make 2 more choices (or not), then hit the next button. In June made these charts with it - http://actualcures.com/heart-attack-medication-results.html It took a while to get what I wanted but I stayed with it because I like the separated wedge look.
