This bar chart visualizes the impact of COVID-19 on female employment by showing the number of employed women aged 25 and older in 2019 for ten countries. The code uses React with a D3.js v5 CSV data loader, mapping each country to a horizontal bar whose length reflects the employment figure. The visualization is rendered as an SVG, with D3’s `scaleBand` and `scaleLinear` handling the axes and bar dimensions, and tick marks drawn manually from the x-scale.
