This “comparative map” compares two different businesses along a timeline with major operations. One company is in the upper half of the map, and the other is in the lower half of the map. The interesting issue here is how the map is easily navigated because of the colour coding despite the density of the relations. You don’t need to follow the lines to see the connections; just follow the colour. The lines are still needed to render the relation density. The map is shown both in the hand-drawn draft and digital versions.
