Recent Tableau dashboard
I've said it before here and at industry events - the only people who use data dashboards are data people. This is why I always found this passage to be true: "More numerate marketing analysts generate insights and reports that less numerate marketers / decision makers don't understand and, therefore, don't use". This is a problem in our industry and why narratives and stories woven in time tested tools like powerpoint still work quite well.
However, there's still no better way to make large data sets navigable and interactive to groups of people (data users) than Tableau. Sorry I can't link to the actual dashboard because it's behind a firewall - but below is my most recent. It's not them most sophisticated data viz - but I'm a little proud it only took me two hours - including data cleaning . . . .
This was a 100,000+ row data file showing ACV (all commodities volume) for every store in the country which sells any CPG products. It allowed us to compare ACV by parent and subsidiary, by region and by store type (grocery, drug, mass, club). I was also able to layer over the geographic coverage of our web properties relative to each retail outlet parent company footprint.
