Jake VanderPlas – Exploratory Data Visualization with Vega, Vega-Lite, and Altair – PyCon 2018




[ad_1]

Speaker: Jake VanderPlas

Exploring a new dataset visually can provide quick intuition into the relationships within the data. There are a few well-developed visualization packages in Python, but they often have very imperative APIs that force the user to focus on the mechanics of the visualization – tick locations, axis limits, legends, etc. – rather than the salient relationships within the data.

This tutorial will introduce data visualization with [Altair](http://altair-viz.github.io), a package designed for exploratory visualization in Python that features a declarative API, allowing data scientists to focus more on the data than the incidental details. Altair is based on the [Vega](https://vega.github.io/) and [Vega-Lite](https://vega.github.io/vega-lite/) visualization grammars, and thus automatically incorporates best practices drawn from recent research in effective data visualization.

The tutorial will provide an introduction to the Altair package and its API, but more importantly will dive into the core concepts of effective data visualization that can be applied using any visualization package or tool.

    This is an incredible visualization toolkit, if we shift our thinking to the "grammar of graphics".

    5 cylinders are in a row. Six and eight cylinders are side-by-side so need to be pairs.

    Jake is awesome… his Pycon videos on visualization are pure magic

    So, basically Altair has two parts API and Translator (Altair Python API -> Altair Translator -> Vega LIte Grammar). Maybe it would be better to develop Translator in JS. Python API will be exactly the same, but Translator could be reused and contributed not only by Python community but by both Python + JS.

    because I love ggplot, I was using R. Now there's no reason to in R anymore (except dplyr, maybe)

    This is the greatest and best visualization library in the world.

    Possibly.

    This is fantastic. I started using Altair yesterday, did quite a bit, got stuck, and then Jake gave me the reference to his Pycon 2018 workshop. This could not be better! 🙂

    This is a great tutorial! I haven't expected Altair to be so differentiating library. Now I definitely have to use it. Selections are just amazing and seem to be much clearer than the ones in bokeh library. Thank you very much!
