Description:

This repo contains web-apps over Evolution Graph Dataset offering capabilities to realize similarity and origins between species.

Evolution of Species - studied by Darwin follows connected graph structure. Here, we've built the dataset on Neo4j using Species as nodes and Category linkage as relationships. For user ease, a JS/SCSS/bootstrap dashboard app is built over neo4j dataset. Also, graphql API server is setup for API support.
