{"version":"1.0","type":"rich","title":"Long Valence Arousal 2","description":"This example visualizes EEG arousal and valence data over time as a thick, gradient-colored line chart against a dark background. It plots the F4 frequency values from the provided CSV files for each epoch, using a blue-to-red gradient to indicate signal intensity. The visualization is built with D3.js, employing linear scales, SVG axes, and a line generator, with small circles marking each data point that reveal frequency details on click. The black canvas and exaggerated chart dimensions emphasize the waveform's shape and peaks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3beb14522764f29afc23be768b32daf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
