{"version":"1.0","type":"rich","title":"act 7","description":"This area chart visualizes employee hires over time, using a steel-blue filled path to show the number of hires per year. The code loads a CSV dataset from GitHub via `d3.csv`, parses dates with `d3.timeParse`, and aggregates counts by year. It renders an SVG area using `d3.area`, with `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom`/`d3.axisLeft` for labeled axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32491f35847845d795dfec9e64e88138?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
