I’ve been thinking of how to organize information to synthesize a logical relationship between space / time (of discovery) and depth of understanding. Forgive the rather crude approximation:

The main parts are as follows:

• Index (left side): a table of contents laying out what topic is currently being viewed (temporal organization). Ideally, a user will read through topics from start to finish to get a better understanding for context surrounding various themes
• Spatial graphing (see below): view ideas with respect to a spatial graph to understand 1. how many units of knowledge each body comprises 2. where in relation to other bodies of knowledge each topic branches from 3. identify logical next “known unknown” to discover
• Display area: detail on specific subject matter
