data visualization (2-d plot) package for smalltalk

Question

Is there any current data visualization or 2-d plot package for smalltalk (squeak or pharo) platform?

something similar to d3js or processing.org, or maybe sdl support to draw lines/dots on the screen?

Answer 2

Have a look at roassal. While it is not exactly similar to d3js or procressing.org it is an interactive visualization engine with a nice DSL called Mondrian to script visualizations.

For further information look at:

• the Roassal homepage,
• the recent examples on it's creators facebook page,
• and the Roassal and Mondrian chapters in Deep into Pharo.
