Kotlin Notebooks: Data Visualization for Developers (No Scientist Required)
summary
Kotlin Notebooks show concrete workflows: use an IntelliJ plugin and a Kotlin kernel to load CSVs and JSON from APIs into a data frame, call GitHub’s API and report counts (30 open issues, 17 bug-labeled), and render bars, pies and a Europe map with plotted attendee coordinates via the Candy visualization libs. Notebooks embed outputs in a single text file for GitHub sharing; avoid heavy batch jobs (one run took 12 hours vs Python’s 2 minutes).
