This simple bar chart shows the amount of buses operating in Oahu over time. As we can see the number of buses serving Oahu has not changed much since bus service was first introduced. While this is not a comprehensive analysis it would appear that the level of service for TheBus has gone down or at least not increased over time since area that TheBus serves has only increased. It would be nice to do an analysis that would include historical coverage areas and bus routes.

One way to increase bus service quality without an increase in funding is by increasing frequency on core routes, hopefully getting some routes to every 10

Diverging Stacked Bar Chart

We create a diverging stacked bar chart to plot a 5 point Likert scale. There a lots of ways to plot a Likert scale but according to Robbins & Heiberger, a diverging stacked bar chart is the best and I agree.

I've used D3.js. There is also an R package by Robbins & Heiberger.

The original can be found at github
