This bar chart displays the budget allocation percentages across different categories, with each segment colored and accompanied by a legend for identification. The visualization is built using D3.js v5, employing the pie and arc generators to create the pie chart, scaleOrdinal with schemeCategory10 for color mapping, and SVG elements for rendering. The legend includes truncated category names and percentage values, with mouseover interactions logging the category to the console. Data is loaded from a CSV file, and the chart is titled "Budget Allocation Chart."
