How can I get the ticks to be horizontally centered on each of the bars?

```julia
spec = data((data=rand('a':'g', 1000),),) * mapping(:data) * visual(Hist)
draw(spec, axis=(xticklabelalign=(:center, :top),),)

```

I think the easiest in AoG is to do this via analyses, in particular here you can use [frequency](http://juliaplots.org/AlgebraOfGraphics.jl/v0.5.2/generated/datatransformations/#Frequency). So something like

```julia
spec = data((data=rand('a':'g', 1000),),) * mapping(:data) * frequency()

```

should do the trick. Histogram is at a bit of a disadvantage for categorical data because the binning gets in the way, whereas `frequency` counts occurrences for each unique value.
