Just a simple makeover this week! I wanted to include a map-as-filter section, but the file with the geographic coordinates couldn’t be opened by my personal freebie account, or by my work’s paid but version 9.3 account. I turned the bar chart into a line chart, and included each year instead of limiting it to the last three. I think this makes it easier to compare years and see the overall trend.
This viz is really very simple, but the underlying data has a lot going on. The region column includes “Total (all TLAs)” representing the entire country. Because the regional values are weighted for population, simply aggregating them would under represent larger, more populous regions, and over represent the smaller ones. Use the Total (all TLAs) rows to represent the entire country, and avoid aggregating the regions.
