{"version":"1.0","type":"rich","title":"area_chart_bala","description":"This area chart visualizes the average monthly profit margin percentage across all regions for a tech product sales dataset from 2021–2024, with time on the x-axis and margin percentage on the y-axis. Using D3 v7, it loads CSV data via `d3.csv` and `d3.autoType`, aggregates values with `d3.rollup` and `d3.mean`, and renders a filled area with `d3.area` and an outline with `d3.line`, both using `curveMonotoneX`. The SVG layout includes time-scaled axes via `d3.scaleTime` and `d3.axisBottom`, rotated tick labels, and gridlines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1bc4db3be2524bce8ae0bed530da30d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
