- Labels – each node and each line has a label, which should be a short expressive text representing the knowledge (it is best to use only one word). Lines explain the organisation of sub-nodes.
- Drawings / symbols / codes – labels can be accompanied by expressive drawings to increase the visual impact.
- Line – connecting nodes become thinner as it departs from the main node.
- Colours – are used to group the various branches of mind map. You can use shades of the same colour to differentiate sub-nodes from the same category.
- Font – can be changed (bold, italic, underline, and colour, different size) to suggest the importance, the difference, the organisation.
- Radial structure – approximatively the same length of lines in a branch.
- Be creative. All ideas welcome.
