how to combine either Rna-seq datasets or results from analysis of Rna-seq datasets to get a visual result

Hey guys, I was doing a project based on Rna-seq analysis of a certain disease, I had taken various public datasets and had analyzed after which I had obtained a specific result. The problem is the result isn’t visually representable(like Venn diagrams or graphs) so I thought of combining either Rna-seq datasets or combining the Deseq2 results of each dataset to get a visually representative result. Which option should I opt for and how do I do it? Thanks for your help in Advance
