We use nvd3 in an analytics dashboard with some success, and some troubles. Simple Excel-like behaviour, such as rotating the axis labels so they don't overlap, require lots and lots of tweaking. Default bar/column chart settings occasionally give mystifying results, like the highest value in the chart plotting above the highest axis value (e.g. 23,600 plots above 22,000 instead of between 22-24k). I'm sure we'll solve these issues, but they are eating up a bit of developer time for things we're used to having work out-of-the-box in something like Excel.
