This bar chart visualizes Olympic gold medal counts across eight sports, showing swimming and javelin with the highest totals while running and cycling have the least. The visualization uses D3.js version 7.8.5, rendering SVG rect elements via a dynamic bar chart that adapts to container dimensions. SVG is selected with `d3.select`, while axes are generated using `scaleBand` for the categorical sports on the x-axis and `scaleLinear` for medal counts on the y-axis. The code implements `axisBottom` and `axisLeft` for scalable gridlines and labels.
