Oahu Trees Visualization Project

This is the final project for for Data Visualization Fall '22.
Oahu Trees is a visualization of the taxonomic relationship between the trees on Oahu, Hawaii. The tree data is sourced from Exceptional Trees on Oahu API, and Wikipedia. The visualizations were built in both Gephi and Graphia.

The final result of the project is an interactive tree (directed acyclic graph) of the oahu tree taxonomic heirarchy.

Clone repo and launch src/sigma/network/index.html locally, to interact with visualization. Click graph nodes to view relation and classification information or use the search box to find a specific tree and filter by group.
