This visualization displays monthly sales data as a bar chart, with the x-axis representing the month and the y-axis showing sales figures. The bars are rendered in steel blue and turn orange on hover, providing interactive feedback. The chart is built using the D3.js library (d3.v7) with SVG rendering, and data is loaded from a CSV file hosted on GitHub via `d3.csv` with `d3.autoType` for type conversion. Axes are generated using `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`.
