- New module `Diagrams.TwoD.Sunburst`, for drawing sunburst
charts.

trails/paths using an API inspired by Metafont. Like
`cubicSpline` but gives you control over things like the
tension/curvature or the tangent at a given point.
- New module `Diagrams.TwoD.Path.Calligraphic` for making simple
"calligraphic" strokes.
- New module `Diagrams.Lens` with lenses for working with
diagrams.

boost.
0.7: 9 August 2013
------------------
* **New features**
- New module `Diagrams.Color.HSV` with an `hsvBlend` function for
blending colors in HSV space.

it to output a doubled path (#13).
0.6.1 (23 March 2013)
---------------------
* **New features**
- New `Diagrams.TwoD.Path.IteratedSubset` module, for constructing
paths using an "iterated subset" algorithm (repeatedly replacing
segments with a given path).
- New `Diagrams.TwoD.Layout.CirclePacking` module for
circle-packing layout
- New `Diagrams.TwoD.Factorization` module, for creating
"factorization diagrams" as seen at
http://mathlesstraveled.com/2012/11/05/more-factorization-diagrams/
and on the cover of Hacker Monthly
(http://mathlesstraveled.com/2012/10/05/factorization-diagrams/).
- `Diagrams.TwoD.Path.Turtle`: generalize `runTurtle` function,
and add new functions `drawTurtle` and `sketchTurtle`.
`drawTurtle` results in a diagram (like the old `runTurtle`),
and `sketchTurtle` yields a path (ignoring pen style commands).
* **Documentation**
- Added lots of example images using `diagrams-haddock`

checking whether vertexes had been already visited.
* **Dependency/version changes**
