Lab 7 - Interactivity
This interactive multi-line chart displays daily average temperatures for New York, San Francisco, and Austin over a year, sourced from a TSV file. The SVG visualization uses d3.tsv for data loading, d3.scaleTime and d3.scaleLinear for positioning, and d3.schemeCategory10 for color encoding. It incorporates a Voronoi overlay for hover detection, d3.zoom with clip paths for panning and scaling, and click interactions on city labels that maintain state, all rendered with d3.line and d3.axis components.
AI-generated descriptionThis line chart is constructed from a TSV file storing the daily average temperatures of New York, San Francisco and Austin over the last year. The chart employs conventional margins and a number of D3 features:
- d3.tsv - load and parse data
- d3.time.format - parse dates
- d3.time.scale - x-position encoding
- d3.scale.linear - y-position encoding
- d3.scale.category10, a d3.scale.ordinal - color encoding
- d3.extent, d3.min and d3.max - compute domains
- d3.keys - compute column names
- d3.svg.axis - display axes
- d3.svg.line - display line shape
