This bar chart displays the number of employees for various service categories, using a horizontal layout where each bar’s length corresponds to the recorded value. The visualization is built with D3.js v7, loading data from a CSV file and rendering SVG rectangles. It employs `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` for the axes, with data mapped from the “No.of Employees” column.
