On many occasions, I need to create some visualised diagrams quickly to help people understand something.

A while ago, I was looking for a handy timeline generator and recently, I wanted to have a chart generator to create nice charts.

Borrowed the “Quick & Dirty” idea, I tried The Pie Chart MakerPiecolor, and Interactivate pie chart. At last, I used Piecolor, a handy tool to create pie charts.  It is not for complicate statistical data, but an easier way of presenting something. Comparing to some tools such as Adobe Illustrator, Piecolor is much easier.

Today, I have a sight of 22 Useful Online Chart & Graph Generators. A very useful sources for my later use.
