About three years ago, I was participating in our weekly Makeover Monday group at work, and happened to immediately know what I wanted to build and got it done in about 40 minutes. A colleague also completed theirs in that time, and so we then shared what we had built with the rest of those in attendance. A couple people asked how we built it, and identified that they were more interested in learning how to build things in Tableau vs why we chose a certain chart, etc. That moment led to starting weekly Workout Wednesday sessions of solving live with the group, and eventually led to my increased participation and becoming part of the Workout Wednesday team. This week we are revisiting that visualization, a dumbbell chart.
I originally learned how to build a dumbbell chart from Ryan Sleeper here, to give you a start on how to build.
