Improving Slack Bot Formatting for Code and Images

It'd be nice if Slack bot formatting was a little better. Of course stuff like React code will never work, but it could be wrapped in a code block or omitted. It'd be nice if a table was wrapped in a code block to be aligned at least. I also noticed if you generate an image, it's not shown in Slack at all, but maybe that's a little harder if that needs to be either public for Slack to see it, or if you'd have to upload it as a file into the message. The use case there is to build a graph image to show as a daily report or something like that.
