Data Visualization with JavaScript

Seems like writing is too individual a task for general recommendations, but, fwiw, I wrote my latest book [Data Visualization with JavaScript](https://www.amazon.com/Data-Visualization-JavaScript-Stephen...) natively in Markdown. No need for a special app or service. [Pandoc](http://pandoc.org) was able to covert it to `.docx`, which was my publisher's preferred format, and also to interactive HTML so that I could publish the full book on my web site [jsDataV.is](http://jsdatav.is/intro.html). My favorite Markdown app at the moment is [Typora](https://www.typora.io)
