Welcome to the Ohio-Five-Digital-Humanties-GIS-Timeline-Project wiki!

The goal of this project is to create an embeddable and easy to use tool for students and academics to utilize to visualize geospatial information from a public Google Sheet on a timeline. The app was built using AngularJS, Angular Openlayers3, and Vis,js.
