-[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.

 ## How do changes get made to Plotly.js?
 
@@ -37,7 +37,8 @@ The basic process for adding new features or fixing bugs is as follows. Please n
 The current Plotly.js maintainers are all employees of Plotly (the company) and one of their primary responsibilities is ensuring the process above runs smoothly. It is worth noting that maintainers and non-maintainer Plotly employees all follow the process above: proposing changes, iterating on proposals and eventually developing and reviewing each other's pull requests. As mentioned above, maintainers look after bug fixes, performance, security, documentation and concerns that impact the long-term prospects for this library.  In terms of development work, maintainers tend to prioritize issues that do or are likely to impact Plotly customers, as well as on [sponsored features or bug fixes](https://plot.ly/products/consulting-and-oem/). Sponsored work proceeds via the process listed above, albeit with the option of conducting portions of the "discussion" step in a confidential setting if desired. Please note that maintainers are happy and eager to help with community-led pull requests, independent of customer-driven development priorities :)
 
 ### The Plotly.js Community
-The Plotly.js community, construed fairly broadly, includes the maintainers and all users of Plotly.js and associated projects ([Plotly.py](https://plotly.com/python), [Dash](https://dash.plotly.com/), [Plotly.R](https://plotly.com/r), [Chart Studio](https://plotly.com/chart-studio) and many others). The community includes people from any background, domain, affiliation and level of technical expertise, for example (but not limited to!) employees of small or large companies or startups; employees or students of universities or other educational institutions; government employees and contractors; employees and volunteers of non-profits; individual hobbyists etc.

 **Anyone in the community is encouraged to contribute to every step of the process described above!**  Creating issues to report bugs or suggest new behaviours is a valuable contribution to this project, as is proposing a concrete set of changes to address issues created by anyone at any time. In  the same way, giving feedback on proposals created by anyone in the community is valuable, as is, of course, development and review work. [Proposing changes to the documentation of Plotly.js or associated projects](https://github.com/plotly/graphing-library-docs/blob/master/README.md) is an extremely valuable form of contribution, as is [asking or answering questions on our community forum](https://community.plotly.com/), as it creates a record of a question and discussion, which others can stumble across later and use to further their own work.
