Can anyone suggest a way to produce an easy to edit/change vertical line with annotations on a web page? This can be anything from an editor with special capabilities to a wiki-like "do it over the web" application. It could even be something that is wholly off-line and generates an image file (though this is probably my least preferred method).
I want to be able to have something which 'flows' down the page, preferably with an actual line of some sort that one can label. Then I want to be able to attach chunks of text description to symbols or markers on the line. Ideally I also want to be able to add further notes/numbers to the sections of the line between the symbols.
Imagine something like a route description with a 'road' running down the screen, distances between places on the road and chunks of description applied to places/features on the road.
Any ideas would be welcome. I guess it's a *bit* like a flow chart but there's no branching required and quick/easy editing facilities are more important than a large range of symbols and cleverness.
