grDRAW

This began as a demonstration of interactive drawing on the 2D canvas with plain Javascript. Then I saw the Tool Jam (May 2024) wanting there to be a "Bug as a feature". So there is a bug but there is also a way to stop it.

The second screenshot on the right was drawn using this program by Léon, the originator of the Tool Jam.

New version 24.10.17:
1. It is now possible to close a polygon by double-clicking the final point, like other programs.
2. A new button [ Show data ] displays the data of all shapes in JSON format below the canvas. This has enabled me to draw shapes easily for other programs.
3. Keys are active: initial letters of the shape buttons; backspace or del to undo polygon sections; z is quicker than spray.

New version 24.5.18: A common comment was that after drawing one kind of object it should be possible to draw another one without reselecting from the buttons. This is now possible for all except [ Polygon ]. There is also a new [ Undo ] button.
