Visualization

• Chart.js 
  • Chart.js can be used to create graphs
  • Custom built-in widgets can be used to simplify the creation of the graph
  • These widgets include, but are not limited to: graph size, location, legend size, legend location, x-axis labels, and y-axis labels.

The Placker plugin for Trello is a great tool for project tracking, allowing story estimation, points, dependencies, etc. directly on Trello.  It will also automatically generate a Gantt chart based on the Trello card setup.  NOTE: this is only free for 2-3 weeks.  A second option (Tableau) is below.

Tableau is a great tool for all sorts of graphics/visualizations of data.  It is also a very useful alternative to Project for making Gantt charts (connect to an Excel sheet, similar to guidelines at https://www.tableau.com/trial/gantt-chart-template?utm_campaign_id=2017049).  Tableau is free for students with a .edu email address (https://www.tableau.com/academic/students).
