Feature request: rounded corners for trace bars

This is a request to pass attributes to trace bar component to adjust bar corner roundness. That way bar visual variety would be extended. Each bar corners roundness could individually adjusted with percentage value from 0 to 1 where 1 is full circle arc.

Attribute could be passed like this: "cornerroundness": { "bottomleft": 0.3, "bottomright": 0, "topleft": 0.3, "topright": 0 }

Maximum arc radius could be set to least wide bar edge width divided by two otherwise there could arise visual problems with bar. Visually that would result that bars would be able to look like this:

+1. I need this as well. Much more subtle but there is a need to fit charts into a brand.
