Observablejs

observablejs combines some features of FRP and some of javascript visualisation and UIs and data dashboards into a single tool.

A large friendly ecosystem of interactive browser-based interactive visualisation tools built on top of D3

Observable Plot is a free, open-source JavaScript library to help you quickly visualize tabular data. It has a concise and (hopefully) memorable API to foster fluency — and plenty of examples to learn from and copy-paste.

The result is a kind of scientific workbook with a unique set of strengths and weaknesses.

Strengths:

1. “More” interactive than most; the tools can be executed in the browser and that means that interative user widgets are easy
2. Light dependencies; it seems to run without a complicated install package like, e.g. python alternatives, and there is a free host for notebooks
3. visualisations are rather pretty

Weaknesses

1. Statistical tools are not powerful (basically only javascript stuff runs)
2. If one of the default visualisations works for you, great, but if not, building a new one is tedious
