This is a six part series, taking you through stages of designing and creating reusable visualizations with d3.js
All visualizations have the same functionality, showcase the individual points with a bar chart and sum up the selected bars.
Part 2. This is showcasing the power of the reusable chart API. This is showcasing the difference between a reusable bar chart and a prototyped bar chart.
These are examples created for a talk (slides and video).
Cheers,
