Create concept maps in XML format with SVG graphics, using ThinkGraph

ThinkGraph is a drawing application specialized for Concept Maps authoring. A concept map is a diagram meant to represent Ideas (each idea being represented by a shape (i. e rectangle, ellipse, image, …).

This diagram becomes a concept map when these ideas are linked. ThinkGraph generates an XML document that can be viewed or modified later by other applications.

ThinkGraph uses standard XML: SVG (Scalable Vector Graphics, and XTM (Xml Topic Maps) for the data part (relations between ideas, e. g parent-child relations). Documents generated by ThinkGraph may be visualized by any SVG application, the most straightforward being Adobe SVG Viewer which is a plugin for Microsoft Internet Explorer.

Unfortunately you can write only in latin-based languages (not Russian, Greek, etc).
