In Part I of this four-part blog post I looked at some basic principles of symbolising coincident lines on a map. In this second part I’ll tackle the issue of disentangling the lines to reveal more. I’m calling this ‘multiplicity’ which really is just a way of expressing the way we might use maps and data visualisations to show multiple pieces of information at the same time.
The short video continues from the previous one and uses the tracklog data from a year of walking our dog, Wisley. In it, I’ll explore how small multiples, and polar area charts (aka coxcombs) can be used to present multiple dimensions at once.
In Part III I’ll be exploring ways to symbolise the intensity of lines across space, and also some more advanced symbolisation techniques to illustrate direction and movement along lines. Part IV deals with animation and movie-making.
In the meantime, happy mapping!
