{"version":"1.0","type":"rich","title":"Dynamic Line II","description":"A multi-panel line chart compares brain-computer interface (BCI) frequency data across four wave types—Alpha, Beta, Theta, and Delta—using dropdown menus to toggle between electrode channels (e.g., F3, F4, O1) for each panel. The main chart visualizes changes in signal amplitude over time, with a separate panel for comparing multiple waves simultaneously. The visualization loads data from CSV files and renders animated SVG paths using D3 v4, with axes built via `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`. A `d3.scaleOrdinal` color scale distinguishes channels, and `d3.schemeSet2` provides the palette.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/949af65523304e719024771e6a2f5aac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
