Books and Resources in Data Visualization

(July  2018)

A personal selection of books, online courses, blogs and website for this summer. My presentation in the Meetup organized in 3 lightning talks can be downloaded here.


Data Visualization for Data Scientists

(January  2018)

A great audience (a full big room) for this lively Meetup session organized jointly with Toulouse data science. My academic point of view on what is data visualization, how to use it, how to do it, based on early statistical literature and my own teaching and research experience. The slides of my presentation as well as a video of my presentation (in french) are full of examples and references.




Shiny is good for you !

(November 2017)

The R package shiny is one of the coolest package in R. In this presentation, I show how to create a first interactive application even without any advanced R programming skills. The slides of my presentation will show you how, as well as the live-coding video (available soon, in french).



Everybody's got to cheat sometimes...

(October 2017)

This month, I have written two new blog posts on the virtues of cheating with data. Yes! Cheating! Well, this is no fraud, nor really "cheating" as you will see.  The first one shows that even well known data visualisation were constructed using some distortions in the data. In the second, I explain why I had to cheat to see into darkness in my own research project.

A video has been recorded during a cool Meetup session. You can enjoy my talk (25mn, in French) by clicking on the image, or simply enjoy the slides (in English).




Why you should never use Radar Plots!

(March 2017)

My new blog post should convince readers that radar plots are source of huge distortions in the representation of the underlying data. We show, using a numerical example, how axis ordering and area representation may change the representation, and thus the perception of the data set.

A video has been recorded during a new session in April, 2017. You can enjoy my  talk (20mn, in French) by clicking on the image, or simply enjoy the slides (in English).

Comments are of course welcome!


Meetup Data Visualization : Maps and Networks: Why and How to visualize?

(February 2017)

A nice and lively  talk with more than 40 people attending. Great discussions and feedback on my controversial presentation.

You can (re)view the slides of the talk, or (re)listen to the video of the complete talk. (in French, 100mn). The slides are in English. Comments are of course welcome!


Meetup Data Visualization 2016

(March 2016)

My first experience, with a friendly community.

 

You can enjoy the slides of this presentation " Data Visualisation for Data Science: Principles in Action", 

You can also play with my new interactive pedagogical application. (Done with R package shiny). You may like (or not) a short video (shot with an iphone) describing that R-Shiny application ( in French).

 

ENSAI 2016

(February 2016)


All the slides form the lectures given during the course for the students at the ENSAI Big Data Master are available to students upon request.
All the R codes used during this course (shiny, googlVis, ..) are in this archive. The data are in an other archive. They should be unzipped in separate folder.

You can also play with my Shiny application on nonparametric regression on the shinyApps platform.

I have also created a file full of references many of them have been used during that course. It is based on the corresponding .bib file (BibTex)


Toulouse School of Economics Workshop (Food Economics)

(March 2015)

You may enjoy this 1 hour video (in French) recorded during my seminar at TSE. The slides are available here.

Café de l'Institut Mathématique de Toulouse (IMT)

(January 2015)

My first public lecture (in French) on the topic, for a one hour tour of the history of data visualisation, under the title "Voir ou ne pas voir: La visualisation des données hier et aujourd’hui". The slides and are available on the website of the café de l'IMT.
