Vega: A Visualization Grammar on top of D3
This makes me feel funny. I can't exactly put my finger on why, but here's an attempt.At first glance the purpose of this project is to make it easier for non-programmers to create visualizations. It's basically d3 without JavaScript, with the added ability to render the visualization using canvas instead of SVG.When I look at the examples, I get confused. I know d3 and I expected to see less complexity, less manual layout setup, and less explicit data dependencies than I would see in the equivalent d3 code. The only thing that this seems to simplify is the declaration of the range of scales when they depend on the width or height of the canvas.But maybe I was mistaken on first glance. Maybe the point is not to make it easy for non-programmers to create visualizations, but to make it easier for programs to make visualizations? JSON is easy to generate and to parse. JavaScript is neither.jheer can you chime in here? Anybody?
