How powerful charts can boost your career

An American accountant managed – as the youngest ever! – to win a crucial election in Los Angeles – thanks to the power of data visualization.

Kenneth Mejia, a 32-year-old accountant of Filipino descent, is very committed to issues of poverty, affordable housing and mobility. In the 2022 elections he ran for “City Controller”, a sort of treasurer, for his hometown of Los Angeles. It’s a department with responsibilities almost as big as those of the city’s mayor and chief justice. For example, the City Controller can commission audits to evaluate the effectiveness of city departments.

Data visualization as election propaganda

Kenneth took a remarkably creative and unusual approach in the run-up to the election: he made imported data about the city instantly accessible and visible. On his campaign website, for example, he created a whole series of interactive maps, reports and searchable databases. He even put up billboards showing with graphs what the anticipated city budget will be used for in 2022-2023.

That transparent communication did not miss its mark. Kenneth won, as the youngest city controller ever. This approach shows how powerful data visualization is to unlock information, which may seem difficult and unfathomable to the general public, in a very accessible way. As a result, citizens not only gain insight but also become more engaged in politics. They become better informed and can vote more knowledgeably.

You too can make a difference thanks to powerful data visualization

Whether you have political ambitions, want to present your scientific research comprehensibly or convince your management of your brilliant ideas… Would you also like to learn how to create powerful graphics that can inform, convince and engage your audience? Charts that not only accurately represent the numbers, but also have a clear message and are attractive to look at?

In the book “Powerful Charts” physicist and Baryon founder Koen Van den Eeckhout explains in an accessible and practical way how this can be done. An indispensable guide for anyone who communicates with and about figures.

Side-by-side comparison of two bar chart versions showing the number of inhabitants per paid political mandate across EU27 countries, ranked from lowest to highest. The left version labels countries with two-letter abbreviations (FR, CZ, SI, etc.), while the right version uses full country names (France, Czechia, Slovenia, etc.). Both show identical data: France has the lowest ratio at 134 inhabitants per mandate, rising through the EU27 average of 385 (highlighted in dark blue), up to Latvia with the highest ratio at 2,570.

Avoiding abbreviations

People are lazy. Make it as easy as possible for them to see what you are trying to show. There are tons of ways to reduce mental noise in your charts, but one of the easiest is avoiding abbreviations.

The uncomfortable relationship between scientific illustrations and AI

Scientific journal Nature devoted the headline of its 23 July 2026 issue to “the human art of scientific illustration in the age of artificial intelligence”. Of course, that sparked my attention.

Gridlines are better than axes

Almost always, gridlines are better than axes. Vertical axes are the default option, and they have been around for centuries, so they are very well known. But they also have downsides. My biggest problem with vertical axes is that they’re often so far away from where the action is really happening.
