Compare! The bar graph is read left to right and seems to imply something about the declining relevance of Billygoats (even though close inspection shows that we expect high growth in billygoats next year). There's data here, but no information. The pie chart contains far less data, but the point is obvious: Trolls are where we should focus our energy. That's why you use it. It makes an obvious point and leaves no real room ...

This guy is so wrong about this that it makes me want to pull my hair out. There is no reason why the bar graph couldn't be as simple as the (always horrible) pie chart.

Cuan cierto. Cómo cuesta explicarle a la gente que una gráfica en una presentación es equivalente a una generalización. Si no transmite un mensaje o si hay que meterse en los valores específicos es que no corresponde ahí. Alternativamente, una gráfica en un ensayo o reportaje deben proveer información y suponen que quienes las ven se van a detener a obtener información.

interesting to compare this with the advice for dashboard design ... perhaps there's a talk in there?

Reminder to myself: "Every chart should visualize one particular point". As a result chart will be simple and comprehensible
