Getting Started

Overview

This project contains two different tech stacks. The data analysis was done using R to generate Plotly compatible JSON. That JSON is then consumed by a React website built with GatsbyJS in order to display graphs on a website.

The top level directory corresponds to the React website. Data analysis code i in the R/ directory.

Get the code

git clone https://github.com/marvinmarnold/oipm_stop_search
