Chartle.net - Create Your Own Free Embedded GraphsThe site chartle.net lets you create your own interactive graphs using any data and publish them online on your blog or website, or use them offline in printed documents. The graphs are created using Java technology.
Types of graps available include: bar, pie, line, area, scatter plot, Venn diagram, radar chart, map charts, US map charts, interactive geo maps, intensity maps, timelines, motion charts (or bubble charts), gauges and org charts.
You create your graph using your own data and then publish, share or embed it on the web. Import functions (Excel, Open Office or text files) will soon be added.
Chartle.net tears down the complexity of online graphing and offers simplicity, ubiquity and interactivity instead.
