Pass default value weights = null to SvgDrawer.draw() from `Drawe…

…r.draw()`

Resolves #171. Although the `weights` parameter was added to
`SvgDrawer.draw()` in f3693b3, the method call in `Drawer.draw()` wasn't
updated correspondingly. `Drawer.draw()` could be amended to also take a
`weights` argument, which it would pass to `SvgDrawer.draw()`, but this might
break existing code even more and would require an update of the
documentation of the README.
