You could transform the 10 point scale to one of dichotomous nature by taking top box scores, those scoring 8 and above, for example. And so then take the frequency count of the top box scores as inputs for your correspondence maps.

Hi,
I have 1000 observations for 6 different products. Each product is rated on
a scale of 1 to 10 on 12 attributes. I want to have a perceptual map for
each product with respect to attributes. The problem is I think

this type of data. If we can transform this scale some how...

Thanks... Your suggestions are welcome
