Data Visualization Goals
Data Visualization Goals
Data Analysis / Mining Goals
Can visualizations answer some of these questions?–Can we predict which area needs more professional development training next year?–Is the response rate on surveys and participant attendance rate co-related?–High volume / variety of data (some of it geo-spatial): survey responses / qualitative assessments / user zip codes / school locations / district boundaries – how do we extract useful information?
Data Analysis / Mining Goals
– Are demographic data (census), income levels, crime statistics, employment rates related to:the outcomes of intervention (for RTI)?the quality of professional development (for SNP)?
– Data collection, reporting and visualization is the first step – finding patterns potentially the next step.
– How do the visualizations scale up from state to national level?
Tools– Drupal CMS (already in-place)– Google Maps API – Gmap module to create an
interface to the Google Maps API within Drupalhttp://drupal.org/project/gmap
– D3.JS (Data Driven Documents) visualizations such as Heat Maps, Chloropleth Maps, Bar charts, Pie chartshttps://github.com/mbostock/d3/wiki/Gallery
– Open Street Maps APIhttp://www.openstreetmap.org/ (Drupal integration?)
Strategy
– Implement geographic map-based visualizations with appropriate amount of information at different zoom factors.
– At high level of granularity link data points on map to bar charts / reports for more detail.
– Analyze data visualizations for patterns.
