The visualization compares 2017 median hourly earnings across eight occupations for females, males, and all persons in the US. It uses a horizontal dot plot with a band scale for job categories and a linear scale for earnings, rendered as SVG via D3 v5. Each gender is color-coded using `d3.scaleOrdinal` with `d3.schemeCategory10`, and the data comes from `earning_averages_by_year.csv`. The chart includes gridlines and a custom legend to distinguish the three groups.
