It's worse than that. Is the size of the circle proportional to the number of incidents, or to the density of incidents? Large circles look like they should the most 'dangerous', but that would imply a high density, which would imply a small circle.
The entire visual representation serves no purpose except to contradict the data it presents.
- DanBC 15y agoHe spent a year creating over 200 visualisations. So, 4.5 graphics a week, for a 46 week year, makes 207 graphics. I'm not convinced that people can gather suitable data, analyse it, turn it into an attractive graphic, and then check the graphic for statistical or numerical or logical or whatnot errors.
