Remember, the SVG coordinate system starts from the top left corner that’s why the range takes the height as the first parameter and not zero. You can add class attributes to SVG elements with the same attr function we used before. A bar chart is drawn between a set of categories and the frequencies of a variable for those categories. The computed y coordinate has to be subtracted from the height of the chart to get the correct representation of the value as a column. The above code snippet defines scales for x axis.

A bar chart is drawn between a set of categories and the frequencies of a variable for those categories. This is how the output looks at this point: g.append("g") So, the x-scale returns a calculated bandwidth from the range and padding provided to the x-scale. Be aware that I use scaleBand for the x-axis which helps to split the range into bands and compute the coordinates and widths of the bars with additional padding.
