Graphs, Charts, and Diagrams are all visual representations of information. They are overlapping but not synonymous terms.
Graphs
Graphs are broken into two main types:
- networks - nodes & edges representing things like the contents of Graph Databases, for example
- plots - which are always to do with the placement of data along axes
Charts
Charts are sometimes plots, but they are a broader category, including things like bar charts Bar Charts, Pie Charts, etc.
Diagrams
Diagram is the most general term, encompassing all of the above.
