The not-so-fun part of working in tourism in the summer: I had to let many customers know their dream trips were already sold out. I had a feeling the time span between the initial inquiry and the desired departure date was getting smaller every day. Naturally, I needed to validate my feelings with hard facts.

For Makeover Monday, I wanted to tell the story of how Facebook is making an effort to make clean and renewable power its primary source of energy. I wanted to be able to sort the stacked bars by energy usage percentage by year. Here's how it's done.

Throughout this series, we've been exploring admission rates at the University of California in Berkeley.

Bar charts are a staple in data visualization. They are often the first chart type that comes to mind when comparing quantities across discrete groups such as sales amount for different product categories. But there are many cases where you may want to take advantage of the width of the bars and their location along the axis to present more information. For example, if you’re visualizing the number of customers by age group and the age groups are of unequal sizes, you may want to use bars of different width.
