Viz 1: Bubbles of "District Success"

The first bubble chart encodes success data in the area of the circles. This sucess data is based on the average percentage pass (percentage pass is the percentage of students who pass exams in a certain school). Although less perceptually-accurate than bar charts, they can pack hundreds of values into a small space.

Viz 2: Mapping Classroom Needs During a Population Boom

The three maps allow us to compare the staff needs of schools over the next 35 years. We used population.io data for the next 8 years, and conservative UN projections to 2040. Using current student to teacher ratios, we project how many more teachers will need to be hired in the coming decades. By 2040, the number of teaching will need to double just to maintain the current ratio.
