This example shows a horizontal bar chart of nitrogen content (AvN) in various crops, using D3 v4 with SVG rendering. The data, loaded from a tab-separated file, is displayed as blue-outlined rectangles, each bar positioned along the x-axis at intervals of 11 pixels and scaled vertically with a linear scale from 0 to 67. The chart is rendered on a black background with multi-colored paragraph text, though the bars themselves are drawn with a simple blue stroke. The visualization focuses on comparing average nitrogen values across different plant species, with bar heights proportional to the AvN field. The bars are placed at y = 200 - 10 * y(d.AvN), suggesting an attempt to map data values to bar heights, though the y-scale is not explicitly tied to the SVG height. The visualization does not include axes, labels, or a legend, and appears to be a basic, unpolished bar chart example.
