This document outlines 8 common mistakes made in graph visualizations: 1) Not setting clear business objectives for the visualization. 2) Not considering the needs of end users. 3) Treating visualization as an art project rather than a tool. 4) Not adding interactivity for users to explore the data. 5) Not properly preparing and modeling the underlying graph data. 6) Not providing guidance to help users correctly interpret the visualization. 7) Attempting to display all nodes and edges rather than focusing on the most relevant information. 8) Failing to address operational questions about security, scalability and maintenance for production use.
