Owner-Occupied Housing Data by County, 3 Ways

This map was produced for a cartographic design course I took in 2021. The course focused on maps as data visualization, and this project exemplifies the importance of understanding the data when designing graphics. In this map, the same data set is represented using 3 different data classifications, natural breaks, equal interval and quintile. The vertical bars show how the data are distributed and where each data classifcation breaks them.

​

As this was not a printed graphic, I chose a dark background for easier reading on screens. The color choices for the data was slightly more complex. The data are sequential, so it's important that the colors show a progression, rather than choosing 5 different hues. 

Other factors in this color choice were color-blind accessibility and contrast with the background.
