A compiler infrastructure for data visualization

2015-07-24

There are many data visualization tools out there. Yet, I believe we're still lacking a robust, scalable, and cross-platform visualization toolkit that can handle today's massive datasets.

Most existing tools target simple plots with a few hundreds or thousands of points: bar plots, scatter plots, histograms and the like. Typically, these figures represent aggregated statistical quantities. Maps are also particularly popular, and there are now really great open source tools.

Perhaps contrary to a common belief, this is not the end of the story. There are much more complex visualization needs in academia and industry, and I've always been unsatisfied by the tools at our disposal.


NumPy in the browser: proof of concept with Numba, LLVM, and emscripten

2015-02-18

It's been a while since I wanted to try to bring some of NumPy to the browser. I've already discussed the motivations for this in a previous post last year. As far as I'm concerned, the main use case would be to enable interactive data visualization in offline notebooks (including nbviewer), which often require client-based array operations for interactivity. In this post, I'll describe a proof-of-concept of compiling NumPy-aware Python functions to JavaScript using Numba, LLVM, and emscripten.


Big Data visualization with WebGL, part 2: VisPy

2014-12-11

In this post series, I'm describing the big data visualization platform I'm currently developing with WebGL. I'll detail in this second post the VisPy library which is the basis of the project.


Writing the IPython Cookbook

2014-10-30

My latest book was released a few weeks ago. This project has been one of the most challenging projects I've ever done, and not necessarily for the reasons I would have originally thought. Here is a little story of those fifteen months writing the IPython cookbook.


Big Data visualization with WebGL, part 1: Overview

2014-10-15

In this post series, I'll talk about the big data visualization platform I'm currently developing with WebGL. I'll give in this first post the main motivations for this project. The next posts will contain the technical details.
