Different system and requirement need different tools, if you prefer text editor. Depending on your preference look at Emacs IPython Notebook, the Jupyter VS-Code extension, or Atom Hydrogen. That will basically let you select chunk of code and execute in a kernel. You do not have to use the notebook format, or the browser based editor.

JupyterLab also allow Rmarkdown-like workflow where code-blocks in a markdown document can be executed to display graph.

I believe the important part is to allow interoperability between different ways people want to work. You can't have 1 size fits all, and there are still a lot of work that can be done to cover some use case.
