{"version":"1.0","type":"rich","title":"A7  Small Multiples Lines chart","description":"This small multiples line chart displays yearly average carrier delay counts for multiple airports, with each airport shown in its own grid cell using a shared y-axis scale. The visualization is built with D3 v6 and renders as SVG, using `d3.csv` to load data, `d3.groups` to nest records by airport and year, and `d3.mean` to aggregate delay values. Each chart includes axes via `d3.axisBottom` and `d3.axisLeft`, a line generated with `d3.line` and `curveMonotoneX`, and hover tooltips triggered by mouse events on data circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9b39333f9bd4dc39184dd23969133f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
