> ...felt a need for a software tool that would help me do things like — plot charts, app prototyping, create dashboards/GUI’s for my personal projects etc. I just needed “some place” to write my code, build small projects or test new ideas. To much of my own surprise, I could not find an easy way to do so.

to the author: Congrats on building and delivering on what's a pretty significant undertaking.

That being said, Smalltalk has had the capabilities you were looking for, for ages, and the tools are incredibly polished because they've been around for so long. On a related note Glamorous Toolkit https://gtoolkit.com/ takes those capabilities and points them at development itself allowing you to use them to help figure out what your code and data are / are doing.

This is an interesting project, but it's just the beginning of recreating what already exists in Pharo smalltalk. https://pharo.org/
