YelpViz
An R package for Yelp business analytics and maps.
R package
Reusable across datasets
Spatial
Choropleth + heatmap
2
install paths (devtools::install_github + .tar.gz)
The problem
Yelp hides location patterns in long lists — a map shows where a business works at a glance.
My contribution
Built a reusable R package wrapping the Yelp API: choropleth maps, density heatmaps, and rating comparisons, with CI and 88% test coverage.
Outcome
A published, reusable R package for spatial business analysis — useful for retail, real estate, or delivery.
What I learned
Test coverage and CI matter as much as the code itself for a package you expect anyone to install. The biggest design call was making interactive Plotly the default rather than static ggplot2 — it doubles the value of the analytical functions because the user can drill into specific points without re-running the analysis.
