Easy Chart Diagramm Tool - Google Chart API
The Google Chart API is an extremely simple tool that lets you easily create a chart from some data and embed it in a webpage. You embed the data and formatting parameters in an HTTP request, and Google returns a PNG image of the chart. Many types of chart are supported, and by making the request into an image tag you can simply include the chart in a webpage.
Currently kind of line, bar, and pie charts, as well as venn diagrams and scatter plots are supported.
