Chart with Google Chart API

The Google Chart API returns a PNG-format image in response to a URL. Example: http://chart.apis.google.com/chart?chs=250x100&chd=t:60,40&cht=p3&chl=Hello|World will return
.

What if I combine a preset URL with the results of a ListPages module ?

chart?cht=lc&chs=600x300&chf=bg,s,EFEFEF|c,s,66CCFF&chtt=Ratings+distribution&chts=0000FF,16&chm=o,FF9900,0,-1,5.0&chxt=x,y&chxl=0:|HowTos&chxp=0,50&chxr=1,0,50,5&chds=0,50&chd=t:0,50,40,35,33,18,18,16,15,14,14,13,13,13,12,12,12,11,11,10,10,10,10,10,9,9,9,9,9,9,8,8,8,8,8,7,7,7,7,7,6,6,6,6,6,6,6,6,6,6,6,6,5,5,5,5,5,5,5,5,5,5,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,3,3,3,3,3,3,3,3,3,3,3,3,3,3,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

Code

The code below was inspired by Erich's ListPages Horizontal snippet. I.e. it uses the backslash "\" both in the prependLine and in the module's body. There is a another hack: I had to add a dummy result, zero, otherwise the series of ratings would have begun with a comma.

[[module ListPages category="howto" order="rating desc" perPage="999" separate="false" _
prependLine="[[image http://chart.apis.google.com/chart?cht=lc&chs=600x300&chf=bg,s,EFEFEF|c,s,66CCFF&chtt=Ratings+distribution&chts=0000FF,16&chm=o,FF9900,0,-1,5.0&chxt=x,y&chxl=0:|HowTos&chxp=0,50&chxr=1,0,50,5&chds=0,50&chd=t:0\" _
appendLine="]]"]]
,%%rating%%\
[[/module]]

Limitations:

the length of the URL
it is currently not possible¹ to dynamically add labels or add other series
