geledek/instagram-account-analyzer ? reverse-engineered prompt

Build me a Python tool that can download photos and post info from a public Instagram account, then analyze the account and turn it into a simple report with charts and a nice poster image.

I want to be able to give it a username, limit how many posts it grabs if I want, and save everything into a folder with the images, a metadata JSON file, and an analytics JSON file. The analysis should show things like likes, comments, posting patterns, caption length, hashtag usage, top posts, and a basic sense of the account’s content themes. It should also generate a clean visual poster with the most interesting stats, and an even nicer premium poster version if possible.

Please make it easy to run from the command line, and include sensible defaults so I can just run it without a lot of setup. If you need to check current docs or library usage online, go ahead and do that.
