Visualizing multicollinearity in Python – I like the network one although it is not very intuitive at first sight. The others you can also get using pandas-profiling.
Advanced Visualisations for Text Data Analysis – besides the suggested charts themselves, it is nice to get to know nxviz. I would actually like to see those charts as part of plotly as well.
Data Tales: Unlikely Plots – bar chart is boring (but informative :), but sometimes we need to think out of the box plot
XKCDs I send a lot – Is XKCD already an industry standard?
5 Tier Problem Hierarchy – I use this framework to think of tickets I write, what is the expected input, output, and complexity, what I expect from each of my team members, etc.
