The following information must be communicated in a general newspaper article: Most living animal species belong to the infrakingdom Bilateria, a highly proliferative clade whose members have a bilaterally symmetric body plan. The vast majority belong to two large superphylla: the protostomes, which include organisms such as arthropods, mollusks, flatworms, annelids, and nematodes; and the deuterostomes, which include the echinoderms, hemichordates, and chordates, the latter of which contains the vertebrates. Which of the following types of graphs should the editor use to best present this information and show overlap between the different organisms?

A histogram is designed to show the distribution of numerical data by grouping data points into ranges, making it unsuitable for displaying relationships between different biological groups. It is not effective in conveying overlapping characteristics among species, as it focuses on frequency rather than interconnections or shared traits.

A pie chart represents parts of a whole, showing proportions rather than relationships between distinct groups. While it can display relative sizes or percentages, it fails to effectively communicate the overlapping characteristics of different animal species, which is crucial for understanding the relationship between protostomes and deuterostomes.

A scatter plot is primarily used to show the relationship between two quantitative variables, making it inappropriate for displaying categorical information like the classification of animal species. It does not facilitate the visualization of overlaps or shared traits among the infrakingdom Bilateria, thus missing the essence of the information being presented.
