“A picture is worth a thousand words. An interface is worth a thousand pictures.”—Ben Shneiderman
What if you could write an interactive data visualization in the same easy way that you can write markdown to create HTML pages. Amit Kapoor and Bargava Subramanian explain how to use declarative markdown-based tool Visdown to build them with ease. Visdown is open source and created using the excellent vega and vega-lite data visualization library. You only need to learn the grammar and principles of interactive graphics, and you can then start your own journey in crafting interactive dashboards.
