Remaking Figures from Bertin's Semiology of Graphics

Remaking Figures from Bertin's Semiology of Graphics

I’ve just published a personal project I’ve been thinking about doing for a few years now: revisiting figures from a 1967 book which has had a big influence on how I (and others!) think about data visualization, Jacques Bertin’s Semiology of Graphics.

Beyond “tidy”: Plotly Express now accepts wide-form and mixed-form data

Beyond “tidy”: Plotly Express now accepts wide-form and mixed-form data

Plotly Express is the built-in high-level data visualization interface for Plotly.py, a leading interactive data visualization library for Python. With today’s release of Plotly.py 4.8, Plotly Express now gracefully operates on wide-form and mixed-form data – not just “tidy” long-form data. These new capabilities dramatically expand Plotly Express’ promise of ‘interactive data visualization in a single Python statement’, by removing the need to wrangle your data into a particular form before plotting.

Montreal Python: Plotly Express and Dash


I recently gave a talk about Plotly Express and Dash at Montreal Python. The description of the talk was, "You start the morning exploring some data in a Jupyter notebook with Plotly Express and after lunch you whip up a web application to give your non-programmer colleagues access to those same insights with Dash, all in under a 100 lines of Python, no Javascript required. This talk will show you how Plotly's open-source libraries fit together to make this possible."

Introducing Plotly Express

Introducing Plotly Express

Plotly Express is a new high-level Python visualization library: it’s a wrapper for Plotly.py that exposes a simple syntax for complex charts. Inspired by Seaborn and ggplot2, it was specifically designed to have a terse, consistent and easy-to-learn API: with just a single import, you can make richly interactive plots in just a single function call, including faceting, maps, animations, and trendlines. It comes with on-board datasets, color scales and themes, and just like Plotly.py, Plotly Express is totally free: with its permissive open-source MIT license, you can use it however you like (yes, even in commercial products!). Best of all, Plotly Express is fully compatible with the rest of Plotly ecosystem: use it in your Dash apps, export your figures to almost any file format using Orca, or edit them in a GUI with the JupyterLab Chart Editor!
