Reducing non-data ink to improve graphical display

In April, I posted on “The Elements of Style” applied to analytic design. Darkhorse Analytics of Edmonton, Alberta, Canada, has this presentation demonstrating the reduction of non-data elements to improve the data-ink ratio of a bar chart. I combined the original and the final images to create a before-and-after image below:

The original bar chart, left, and the re-designed bar chart, right.

Re-designing reduced the image size to less than 10% of the original, a huge reduction which indicates the potential for expediting image loading.
