Dr. Geo is a GTK interactive geometry software. It allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is useable in teaching situation with students from primary or secondary level.

Besides the general file format, Dr.Geo also provide a dynamic graph definition using the language of Scheme. This module save any Graph object into Scheme language, which can be evaluated and rendered in Dr.Geo.
