I have seen many questions related to occlusion of labels on pie charts and have always suggested that the problem should be solved by moving the labels outside the pie chart, or by rotating them to align with the axis.
The solutions I have suggested often is to rotate the label but it has never quite satisfied me. Part of it was the horrible font rendering done by some browsers and loss in legibility that brings and the weird flip when one label crosses over the 180° line. In some cases, the results were acceptable and unavoidable, e.g. when the labels were too long but in most cases, they looked just clumsy.
I would consider using a different form of visualization for the data usually, but out of curiosity, I thought that I should try to see how difficult is it to actually do it.
The results are on this Plunker.
