Introduction
It’s no surprise that many analysts tend to enjoy looking at data via a scatterplot. It’s a great way to show correlation across two measures for a cohort of dimensions. Additionally, one of the most popular charts of all-time is a line chart which shows historical trends. So how we do show correlation of two measure over time? Well one option is a combination line chart with a lines per measure. This chart type is quite popular but a more interesting option is, of course, the connected scatterplot.
That’s what this challenge is going to focus on. But we’re going to follow data viz best practices and only going to connect the right dots at the right time (when the user wants to)
Can you do it?
