Description

I have three groups of points with different radiuses. With fixed set of point.padding, the problem will look like below. The big circle will cover part of the label. But if increase point.padding, the small circle's label will be too far away. Is there any work around for this? Thanks. image

Research direction
Investigate the current implementation of point.padding in the ggrepel source code (likely in R/ directory). Understand how point.padding is applied to each point. Consider whether to allow a per point padding value, perhaps by passing a vector or using a mapping aesthetic. Check existing comments in issue #83 for user discussion about workarounds. Evaluate the computational cost of allowing variable padding.
