I created a plugin for this feature, see http://www.highcharts.com/plugin-registry/single/5/Rounded-Corners
Edit 2014-05-07: Co-worker Stephane also has a nice drop-in code snippet for creating custom shapes: http://jsfiddle.net/highcharts/My9Qp/Leon Hwang supported this idea ·

Definitely. We are looking for this feature and we don't wanna have to switch to a different library for this.
