How cnfeffery/datasciencestudynotes works
This repository is a collection of article attachments and runnable examples, not one integrated application. Its most developed thread teaches Dash app construction: users interact with controls, callbacks update rendered results, and later examples add uploads, tables, routing, mapping, and persistence. Separate historical utilities demonstrate OSM road-data downloads and map-service clients. The graph groups related examples as capability areas; it does not imply that separate lesson scripts call one another. Evidence is limited to the README excerpt, file tree, and sampled source files.
