Using hierarchical diagrams can be useful when presenting or arguing the importance of various topics.
1. Use Size. Almost every hierarchical diagram you’ll find will use size to demonstrate a visual representation of significance. Make sure when you’re tinkering with size that you make the differences noticeable, so it’s easier for your readers to understand.
2. Bright Colours. Having lots of colour in diagrams makes it easy for readers to quickly distinguish what you’re comparing. The more noticeable your colours are, the easier it’ll be for your reader to understand what you’re comparing.
3. Creatively Use Shapes. Looking at a bar/line/pie graph can be boring for your readers, so think outside the box to highlight your hierarchy. Move your shapes around to best use space, as it creates a more interesting look to your diagram.
