What is the best way to represent Spearman’s correlation graphically? For my thesis research I have to do Spearman’s correlation tests on a set of ordinal variables. I would like to represent the correlations graphically to include them in the report and give a clearer idea of what is the relationship between the variables.
Since the Spearman’s is on ranks, is it most appropriate to make a scatter plot with the ranks or with the actual data?
I was also wondering whether it is appropriate to include the graphs with data that do not give significant results, or if only significant ones should be represented.

There is a case for both graphs. A scatter plot of ranks shows, as it were, Spearman correlation's view of the data; a scatter plot of the original data shows your view of the data. What might be especially interesting is to show some examples where the relationship is monotonic but strongly nonlinear.
However, a problem could arise with ordinal data where there may be many ties, so you would need to think how to show the frequency of each distinct pair of values directly.
There is scope for a scatter plot matrix or pairs plot to show many plots in one image.
Your question is drifting into territory where only your advisor or supervisor or someone familiar with local rules or styles at your institution  can advise on expectations.
Further, much depends on how far the readership is expected to be familiar with statistical methods, or (not at all the same thing) how far you are expected to be able to explain the methods you are using, including their strengths and limitations.
