{"version":"1.0","type":"rich","title":"Arousal Layer","description":"Arousal Layer visualizes EEG electrode data from channels F3 and F4, plotting alpha and beta frequency band values over time. The visualization, built with D3.js v3/v4, renders multiple line graphs as SVG paths with animated transitions, allowing users to toggle between AlphaF3, AlphaF4, BetaF3, and BetaF4 data series via buttons. The chart displays epochs on the x-axis and amplitude values on the y-axis, with a legend indicating arousal periods across different epoch ranges. Interactive zoom controls (plus/minus buttons) enable detailed examination of the time series data. The visualization uses D3's scales, axes, and line generators to render the physiological measurement data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e6f89fa17b94ed9b73250c262a04107?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
