Color gradients?
It’d be nice to have a way to specify a color gradient, presumably spanning the chart area in either x or y, with some given color stops.
Gradients on links, bars, and rects would also be lovely to indicate direction, as here:
may be fixed by #700 (it doesn't allow the gradients to be based on the data, but we can't realistically cover every use case: if one needs to compute gradients from data, there is still room to do it with vanilla JS or D3 (?))
Pretty close, but it would be much nicer if you could express inline syntax for a gradient rather than having to create the linearGradient element in SVG. I think we could do this by writing a CSS parser for the linear-gradient function. This would create a linearGradient element under the hood with a dynamic id.
