Wordcloud creates a messy image

Question

I'm trying to use Wordcloud built in function (I'm using v10.3.0.0) but the result is not good. I'm using a list with expressions and respective weights:

This is the result when using

WordCloud[Scores]

I get a "better" result with:

WordCloud[Scores, WordSpacings -> 20]

but in this case there is too much space between the words... So, how can make a nice wordcloud for this case?

EDIT: So this is what gives when using

WordCloud[Scores, WordSpacings -> {10, 8}]

and this is what I wish I had:

It was created using http://www.wordle.net/. I want to recreated it using Mathematica because I want to manipulate to colours, for which case Wordle is quite rigid in the options.

Answer 1

I find a decent result by using the two-argument version of WordSpacings, where the first number is along the word's direction (horizontal here) and the second is perpendicular to it (vertical here). Further, if I give it the same image dimensions as the wordle version above, the result is very similar

WordCloud[Scores, WordSpacings -> {10, 3}, ImageSize -> {1181, 498}]

And it is pretty easy to apply a custom color to each word. As far as I can tell the only argument given to ColorFunction is the weight, so we can't use that very easily), but we can use Style. Here is a list of random colors,

colorlist = RandomColor[Length@Scores]

Now I just apply Style to each word in the list,

WordCloud[
 MapIndexed[{Style[First@#1, colorlist[[#2]]], Last@#1} &, Scores], 
 WordSpacings -> {10, 3}, ImageSize -> {1181, 498}]
