This visualization displays salary range data from a CSV file, plotting each range as a rectangle with a fixed width of 300 and height of 500 pixels. The rectangles are rendered in steelblue using D3.js, with counts parsed from the data. The code uses D3’s `select` and `csv` methods to load and bind the dataset, but the rendering is incomplete as it does not position the rectangles based on salary values. A sidebar is included in the layout, along with basic styling for text elements.
