Working with scales
In data visualization, we will always have to deal with mapping our dataset to a specific range of pixels. Let me give you an example. We have a dataset [0, 2, 4, 6, 8, 10] that we want to display for mobile and desktop devices. On mobiles, we want to display the dataset with a total width of 480px and on desktops with a width of 1024px. In order to draw the dataset on these pixel ranges, we need to map it to these ranges.
