 ## Plotly.js vs Plotly.py and Plotly.R
 
-[Plotly.js](https://plotly.com/javascript) is a standalone Javascript data visualization library, and it also powers the Python and R modules named `plotly` in those respective ecosystems (referred to as [Plotly.py](https://plotly.com/python) and [Plotly.R](http://plotly.com/r), respectively, for clarity). There also exist Plotly.js-powered libraries for other languages such as Julia, Scala, Rust, .NET and even C++!

 The basic architecture of Plotly.js is to accept [JSON](https://json.org/) representation of figures that adhere to the [figure schema](https://plotly.com/javascript/reference/index/) and draw interactive graphical representations of these figures in a browser. Libraries in other languages like Python and R provide idiomatic interfaces for users of those languages to create and manipulate these JSON structures, and arrange for them to be rendered in a browser context by Plotly.js. This means that in many cases, when a Python or R user wishes to add a feature to the library they know as `plotly`, the relevant changes must be implemented in Plotly.js, in this repo.
