@KatieeKae A cladogram is a visual, hierarchal diagram (tree like) of the understanding of a group of species using some trait as a criteria.

OpenStudy (praetorian.10):

A cladogram is a diagram used in cladistics which shows relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants or how much they have changed; many evolutionary trees can be inferred from a single cladogram. A cladogram uses lines that branch off in different directions ending at groups of organisms. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which would have the combined traits of the lines above it. This hypothetical ancestor might then provide clues about what to look for in an actual evolutionary ancestor. Although traditionally such cladograms were generated largely on the basis of morphological characters, DNA and RNA sequencing data and computational phylogenetics are now very commonly used in the generation of cladograms.
