{"version":"1.0","type":"rich","title":"Second Valence Arousal","description":"This example plots time-series measurements of arousal and valence from an EEG dataset (channel F4) as an animated, interactive line chart. The visualization displays one of three data segments at a time, with buttons to switch between arousal and valence signals, or to cycle through the segments. The chart uses a gradient stroke from blue to red to encode the signal amplitude, while individual samples appear as small yellow dot markers on click. The code uses the D3.js library, specifically `d3.csv` for data loading, `d3.scale.linear` for axes, and `d3.svg.line` for the path geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e67b582aded4e30b3af4e4118ff8431?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
