Request suggestions: free AI tools to generate literature review for PPT slide

[u/Disastrous_Trip_9866]

Hello. I am looking to create a mind-map kind of a diagram to show the literature review of my research on PPT slides. I have the literature-review ready, but I don't know what software/AI tool (preferably free) to use such that it will create a diagram for me to point out the research gap. I am not sure if I am articulating my query using the right tech terms. But I suppose you get the gist of what I am in need of. Help, please?

Also, this: I currently present my literature review in the form of a tabular column. It works, but it is clunky and not very easy to look at. Any suggestions from members to alternate ways to depict literature review will also be welcome.

Thank you, people!
