I also do instructional design so this is a topic I've thought about...I don't feel like I have a good sense about "used most" across the entirety of data visualization creators, I can speak to what I find most useful from the list you posted:
- histogram. This is incredibly useful for validating data before we ever get to what we typically think of of "analysis" and "visualization", they are a go-to chart type for me.
- Pareto charts. Whether we're trying to identify most profitable products, highest volume customers, or the largest sources of defects these are really useful charts.
Beyond that I have a soft spot in my heart for control charts, I think they are perhaps the most under-utilized chart type. Very often the success or failure of KPIs in KPI charts is due to common cause variation that would be revealed (and lead to more effective interventions for performance improvement) if more people were trained in using control charts. Various kinds of KPI charts are (IMO) more commonly used than control charts, though.
Happy New Year! Thanks for your response. I will pare my Adv. Visualizations section down to the four you mentioned--histogram, Pareto charts, control charts and KPI charts. Even though I originally only wanted three, the reasoning you put behind keeping control charts makes sense. If understanding control charts better helps learners understand KPI charts better, then it makes sense to teach both!
Thanks again! Happy designing!
