This visualization charts alpha and beta EEG frequency bands from electrodes F3 and F4, alongside a derived arousal metric across epochs. The SVG line chart plots F3 and F4 values from CSV data, with interactive buttons to toggle between frequency bands and zoom controls using d3.behavior.zoom. A legend distinguishes the colored lines, and clicking the chart updates the axes dynamically. Data is loaded via d3.csv and rendered using d3.svg.line and d3.svg.axis.

AI-generated description

An example showing the capabilities of VizHub:

  • Loads D3 via UNPKG.
  • Demonstrates use of import from "d3".
  • Demonstrates use of import from local ES6 modules.
