Book Concept Count Histogram

About This MicroSim

This histogram visualizes the number of concepts in each of 55 intelligent textbooks generated using the Learning Graph Generator. Each book's concept count comes from its docs/learning-graph/concept-list.md file and is summarized in book-concept-counts.csv.

The horizontal axis is divided into 15 equal-width bins covering the observed range of concept counts. The vertical axis is the number of books that fall into each bin. Hovering over a bar shows the exact range, the count of books in that bin, and the names of the books (up to 8) along with their concept counts.

How to Read It

  • A bin labeled 200-236, for example, contains every book whose concept count is at least 200 and less than 236.
  • The tallest bin marks the most common concept-count range.
  • Outliers on the right tail are textbooks with unusually large concept inventories (Calculus at 680, Information Systems at 580, Learning Linux at 550).
  • The single book in the leftmost bin is the lowest-count textbook (Unicorns and Other Mythical Beasts at 140).

Data Source

Concept counts are extracted from each textbook's docs/learning-graph/concept-list.md by counting unique numbered list items. The summary CSV lives at /sims/concept-analytics/book-concept-counts.csv.
