Description:

Vega is a visualization grammar. It has a declarative format for creating, saving and sharing visualization designs. The data viz is described using JSON. IPython has become the preferred editor for a data analyst/data scientist using the Python stack. Unfortunately, there's no good ipython to vega translator yet. Vincent was trying to do some, but was discontinued earlier this year. The current translator is still a WIP.

The aim of this dev sprint is to improve upon what currently exist. The broad idea is to to allow anyone to write simple declarative stuff like position (x,y), size, color and shape for a pandas data frame, and then convert it into a json spec that can be used in vega to render a visualization.

All ideas/comments will be discussed/posted here: https://hackpad.com/PyCon-IN-2015-DevSprint-Viz-Eqkdzm3EFDR

Why would I want to attend this dev sprint?

On top of my mind, I can think of the following points

  1. Learn about developing tools for data science
  2. Get mentored on various visualization topics from experts
  3. Contribute to open source
  4. Have fun !

Prerequisites:

Some knowledge of Python. Some knowledge of Pandas would be ideal.

We will provide directions on the action items during the day.
