Colorado Schools: Filter

Idea

• I wanted to create a simple, interactive visualization with minimal scrolling.
• Use the mouse to drag/create filters on the many variables in the data, which changes the histograms/map.
• You can make filters for each variable, letting one ask many questions.
• I also added a few example questions with links to get people started.

Purpose

• Given the data (school grades, demographics, location, etc)
• Guide users through previous analysis (questions, observations).
• Allowing filtering of relevant features (location, grades, demographics, etc) for their own exploration.

Future Features

• Add more questions and analysis
• Further filters
• Different views of the data
• Change colors/size of points on map

Used

• HTML, JS , CSS
• Bootstrap, jQuery
• Libraries: d3.js, crossfilter.js, topojson.js
• Tools: Sublime Text 2, Yeoman
• Data: node.js to parse csv's
• Hosting: Heroku

Feedback on data provided

• (1,2,3 = decrease, same, increase) in grades - isn't that helpful
• 1-13 = Grades F-A - use percentages?
• missing/inconsistent data
