{"version":"1.0","type":"rich","title":"BarChart","description":"A bar chart displays alpha power values from a node labeled F3 across successive epochs, with each bar’s length encoding the numeric value and its vertical position mapping to the epoch index. The visualization uses D3 v6 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `csv` to load and parse the dataset. Bars are rendered as SVG rectangles with a steelblue fill, while the chart includes axis labels and a title. The code parses all numeric columns from a CSV file before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0bd1801fd222420186c1b36fe0b56807?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
