Using d3.v5 and SVG, this example visualizes the gender wage gap in the US by plotting average yearly earnings against eight occupation categories for 2017. It shows income differences across three groups: females, males, and persons overall. The visualization uses d3.csv to load the data, filters for a single year, and then employs d3.scaleOrdinal and d3.schemeCategory10 for color coding. Linear scales (d3.scaleLinear) and axes (d3.axisLeft, d3.axisBottom) render the chart, with gridlines from the left and bottom axes.
