MathGraph32

MathGraph32's JavaScript version runs on the web or desktop and opens older Java figures; the Java application itself is obsolete. The project describes GPL3 licensing. Its linked JavaScript FAQ shows constructing a polygon before measuring its area, with a named result that is valid only for a non-self-crossing polygon. Function curves can be limited to an interval, with the angle unit checked for trigonometric work. Deleting an object in the construction list can also delete its dependent objects. For centimetre-scale printing, the guide exports PNG with a figure unit; later word-processor resizing changes the intended scale. The broader environment supports real/complex functions, matrix work, reusable constructions and dynamic web export.
