Intelligently position labels of varying sizes

[jolars]

• [x] Make labels optional (perhaps not necessary because of text arguments).
• [ ] Place labels outside the diagram with an arrow pointing to them if too large to fit.
• [ ] Intelligently break labels with separate words to fit inside diagrams.

Thanks so much for this package, @jolars - I've embedded the visualisation into Power BI using their support for R. This was my first outing with R, and once I'd gotten the DAX measures for each of the segments in the diagram sorted implementing a working graph was well easy. Formatting, as ever, took the most effort (apologies for overwriting your more accessible colour scheme)! Only thing I'd like to improve is to put the labels on the outside of the circles/ellipses, hence the upvote for this idea...

Great to see, @poeadam, and thank you for your support! It's definitely time I got around to take another look at this. If I get some time over in the coming weeks I'll see if I can make it work.
