I saw your already covered the Paris regional public transport map before, and I was wondering whether you had seen the very cute compact version you can see on the Vianavigo site when you zoom out. What do you think?

Tiny and adorable, this diagram really only exists to say, “Hey, you’ve zoomed out too far!” Impressively though, it retains the same structure as the more detailed maps of the other zoom levels, which gives a seamless effect when zooming in and out. Each level of zoom on the site introduces more detail – it’s only when you zoom all the way in that all the Métro stations are labelled, for example – which is a nice use of the interactive map technology. Viewing maps online in small viewports is not my favourite way of doing things, but at least this map has considered its content at each view level: regional overview drilling down to a detailed station-by-station view.

This tiny diagram might only be a placeholder but all the terminus stations are labelled, so it still has some use. And with its thick lines and white station dots, there’s just a hint of the old Rudi Meyer RER diagrams in it as well. Perhaps some parts are overly detailed (the logos for the Orlybus and CDGVAL services; the under-construction part of Line “L”), but it still holds together fairly well. I like it as a tiny little “rough sketch” of the regional lines, inviting you to zoom further in.
