"Although his work was very original, it is typical of the 50s to 70s. He was not the only one to analyze images. Roland Barthes has worked on advertisements, Pierre Bourdieu on photography... His work can be considered as a typical structuralist analysis, because he focuses on the relationship between elements of graphics, and not on the elements themselves. And it is a very modern work, which proclaims that graphics are not static. Graphic mobility is a way of processing information, as all those who have used Bertin's matrices have noticed. His heritage goes far beyond Geography and has been very useful in visual data analysis."
