Discord Message History Grapher

Setup

Clone git repo (or download as zip + extract)
Install NodeJS 14+
Run npm install
Copy config.example.json to config.json
Fill in the required fields in config.json (token = discord token, channelId = id of the channel to scrape, viewer port = the port the webserver runs on that lets you visualize the data, fetchDelay = delay in between fetching messages in milliseconds, recommended to increase this for large channels to prevent account being locked)
Run node app.js, wait for scraping, then open localhost:8080 in your browser!
