Scalable Vector Graphics
Thinking about how Jo could implement her “Malcolm is the centre of the universe” system (luckily Malcolm wasn’t around to hear my poor “ah, Malcolm in the middle” joke…), led me to look into Scalable Vector Graphics. It’s a nice way to draw diagrams by the looks of it, although it hasn’t made it into browsers by default yet.
There an FAQ here, and Adobe has a viewer available as a free download, and a pretty good tutorial which introduces the basics.
Plus, whilst getting the link for the Green Dragon for the last post, I found that the Cambridge Pub Guide has an SVG version of their pub tube map.
