Hi

There is a visualization of your company vs competitors based on a subjective scale of several parameters in blue ocean strategy called strategy canvas. I attach a few examples.

I personally find the use of a line chart a bit confusing. Any ideas on alternative ways to show the data? Maybe small multiples bar charts?

Peter,

I would not display this information as a graph at all because the data does not appear to be quantitative (i.e., based on numeric measures) and is entirely subjective. Displaying this information as a graph gives it an appearance of objectivity and accuracy that does not exist.

I think what you're looking for is like a feature matrix:

Of course you'd have to decide how the information used to plot the example charts translates to something like this though.  In the example, I just imagined a line through the middle, anything above the line was offered, anything below was not, which could very well be wrong.

To me, it seems very much like this example:

It seems to be a rating scale, which is, of course, subjective, but still deals with numeric information.

How worthwhile it would be to chart the ratings depends on the robustness and validity of the rating system itself, I would say.

We don't actually know if this is based on a numeric rating system. The examples display no scales. We can't say anything definitive about this without better understanding the data, how it is derived, and how it is used.

Yes, I guess what I meant to say is "If we can assume that the ranking system is numeric and robust..."

To my understanding it is a subjective opinion to what extent the companies offer unique venues, star performers etc and not based on a numeric rating system but I could be wrong.

sorry for the belated reply, but how about a spider / radar chart? 12 dimensions for 3 items is manageable (see below; random numbers)
of course, assuming that the data it is indeed numeric and not binary...

Bogdan,

Assuming that the data is legitimately numeric, bars similar to the solution that Peter suggested work better than a radar graph. It is easier to read a bar graph, in part because of its linear as opposed to radial design. We can usually scan information more efficiently when it is linearly arranged. If a radar chart were a good solution, a line representing each circus would be easier to read than your examples with area fills. Radar charts are almost never the best solution.
