{"version":"1.0","type":"rich","title":"Valence Layer","description":"This interactive visualization charts valence values derived from alpha and beta EEG frequencies recorded at the F3 and F4 electrode sites. Users can toggle between the four frequency-channel combinations via buttons, with the colored line representing the selected signal and a zoom feature for closer inspection. The example loads data from separate CSV files for each frequency band and uses D3.js version 4 to render the line chart as an SVG with animated transitions. The underlying code also demonstrates importing modules from local ES6 files and loading D3 via UNPKG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5f02fd566c64efdaf8ae4c5198e6bd0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
