Subject: [9fans] Road-highlighting like in games/roads

2nd Edition Plan 9 had a neat program, games/road, which
provided a map of the US with data on roads and the like.
Among other neat features was the ability to highlight
just requested features. For example, you could have the
map show just I-80 and US-22.

I've got a project (not related to Plan 9) in which that
particular function would be very useful, but I've never
seen it in any other mapping application. Has anyone
seen such a thing elsewhere?
