I have just added an online chart maker and a mind map building component for developers to mind-mapping.org.
DIY (Do it yourself) Chart is a web-based tool that lets users make charts from static or dynamic data. It operates on-line and responds dynamically to changes in the data, without a need to reload the web page. These are just a few of the chart-styles available:
The charts/graphs can be generated using any scripting language. And you can embed charts in web pages much as you do with YouTube videos – by just pasting in HTML code.
TreeGX is a WinForms component for VS.NET developers to embed in their products, when they want to represent tree or outline-format phrases in a mind map or bubble diagram format. It is not a stand-alone product.
The web site says “Visualize decision trees, create mind maps and more”.
