it would get the point across much faster. but it would be a less enjoyable interaction. this is an example graph that i'm never going to look at ever again. i don't even need to care about information. like, it's mostly irrelevant to me. it's a toy example. and it's a bit of a fun example to make people go 'huh, this is a cool vizualisation package'.

if i had a dashboard i needed to use at work set up like that i'd have a bloody conniption after a week. but this isn't a work dashboard -- it's a functionality demo and i'm more likely to remember echarts now as a result (purpose of examples achieved).
