Open Flash Chart

Open Flash Chart 1.x was great and it works like a dream. 
This is a little gentle propaganda for the project. Like all opinions, disregard it and make up your own mind.
Edge cases such as

• tooltips encourage user interactivity and data exploration
• what happens to the tooltip when two points are in the same position?
• you can re-size the charts
• missing data
• save the chart as an image
• You can highlight or emphasize one (or many) points

PC Pro loves open flash chart.
