A watermelon graph is appropriate to showcase each series of data because it visually represents the breakdown of a whole into its individual parts. Just like a watermelon is divided into sections, a watermelon graph divides a set of data into categories or segments, allowing the viewer to easily compare and contrast the different parts of the whole. This type of graph is effective for presenting data that has distinct components or categories that together make up the total. Additionally, the use of color in a watermelon graph can help to differentiate between the various segments, making it easier for the audience to interpret the data at a glance.
