JavaScript has eaten Data Visualization, too.

JavaScript

Software is eating the world. And JavaScript is eating software_{incldues data vis}.

Example # 572639: You can now use JavaScript functions in Excel. https://t.co/x2sNkHv8FR

Why JS (1)?

Think of JavaScript as a Dante-like figure, moving from the Netscape rush-job dynamic language hell of the '90s to paradise. Programming Language Theory is Virgil. I won't make more analogies that put real people in circles of hell (but I could!). Anyway, no: JS is not the devil.

Why JS (2)?

• Web GL (power of the GPU and the CPU)
• Machine Learning (TensorFlow.js - Google)
• Scientific/information visualization (google IEEE VIS 2019 - IEEE)
• Development (VS Code - Microsoft, Atom - github)
• ReactJS (Facebook), Angular (Google/Microsoft) etc.
• ReactNative (smartphone apps transpiled)

Web mapping (Xerox)

Web mapping (now)

Web mapping (leading libraries)

Web mapping (MapboxGL)

Data vis

• IEEVIS 2019 in Vancouver best paper tech stack? Yep, the web.

Turing eATlas

Techstack

• WebGL powering Uber’s DeckGL
• Uber’s baseweb.design to manage HTML
• Uber’s React-vis powering the charts/graphs (D3)

Aim?

• Dissecting geospatial datasets.
