Well nobody seems to have taken up the challenge John, so here goes.

In summary the graphics show the properties of brands of full-fat 
milk sold in Spain. Some of them are supermarket own brands and 
others general branded products. By clicking on the rectangular 
buttons across the top you can select which criterion to look at and 
when you do there is usually an explanatory text shown upper-left in 
the plot. By default you get overall quality rating.

Good features of the graphic seem to me to be that the brands are 
always in the same order so if you buy your milk from (say) the 
Eroski supermarket chain you can track it easily through the 
different criteria. Another good feature for me is the fact that the 
underlying values do not clutter up the visual presentation but can 
be retrieved by hovering over the sector

Several of the criteria are inherently continuous but have been 
categorised which seems to me a shame.

Overall for a newspaper graphic it seemed of good quality to me but YMMV.
