Show HN: gridvisual – search and visualize EU data (D3.js)

- It'd be handy to highlight search terms and maybe sort by some relevance measure

- For example in this graph:

http://www.gridvisual.com/datasets/unemployment-rate-by-sex-...

It'd be handy to be able to see both sexes as different lines on one graph. If I scroll down enough to the widget that switches between male-female-total, I can't see the graph anymore which makes it difficult to compare data across facets. There's an interesting tradeoff here of putting the controls on the side for easy access but then having to make the graph smaller.

I like the idea of the subscribe feature.

In any case, good stuff! Is this raw d3?
