This histogram visualizes the distribution of power data values from a CSV file, grouping the data into eight bins spanning 0 to 800. The code uses p5.js to load the external dataset in a `preload()` function, then draws vertical grid lines and cyan bars, with each bar’s height scaled proportionally to the count of values in its bin. Axis labels and bin ranges are rendered directly on the canvas, and the visualization’s fixed dimensions and styling are defined through p5.js canvas drawing commands.
