This bar chart displays the decibel levels recorded for six consecutive days, from day 6 through day 10, using purple bars on an SVG canvas. The data, loaded from a local CSV file, is plotted with D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the y-axis. Axes are generated using `axisLeft` and `axisBottom`, while the bar widths are set via `scaleLinear` based on the maximum decibel value. The chart uses a top margin of 20 pixels and a left margin of 100 pixels.
