Social Media Portfolio

It all started with the Pie Chart Pirate social media accounts. This example did particularly well with over 200,000 likes across Reddit and TikTok.

The focus lies on Science and Technology as my interests lie in these areas, but I sometimes create a visualization about the economy or public health.

The software to create these visualizations is created in-house. It uses the Python programming language. This code will be published at some point, stay tuned on our Instagram account for that!

Story so far

When Covid-19 first hit, I found myself with more time on my hands. I decided to take up my old hobby of making data visualizations again. But this time bigger and better under the name of Pie Chart Pirate.

The visualizations got quite some traction on social media platforms with over 30,000 followers and over 20,000,000 views. On top of that, I got contacted by quite some people to make custom data visualizations as a freelancer, and this is how SJ Data Visualizations was born.


About Sjoerd

Sjoerd Tilmans is an engineer by day and a data enthusiast by night.

He is originally from The Netherlands where he studied Mechanical Engineering. During this period Sjoerd fell in love with simulating physical processes, mainly moving and deforming objects.

Now working for a software company in the UK, Sjoerd fell in love again, but this time with all things data. Sjoerd combined the smooth motion of physical simulation and everything he learnt about data into SJ Data Visualizations.
