Jesus. I've been trying to get visualizations now for 6.5 hours. I read that I need community extensions. No software manager I have (including Synaptic) says anything about community extensions or visualizations. I've tried every search I can think of and read every help file I could find. None of them are actually helpful. I just want visualizations. It does't seem like finding them should be an all day project. I'd really appreciate some help here.
