{"version":"1.0","type":"rich","title":"VizHub User Count Over Time","description":"This visualization tracks the growth of VizHub’s user base from its August 2018 launch through December 2019, using a time-series line chart with green circular markers for each recorded data point. The chart encodes date on the x-axis and cumulative user count on the y-axis, revealing a steady upward trend with more pronounced growth spikes in mid-2019. Built with D3 v4, it uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.line` with `d3.curveMonotoneY` for the smoothed line. Data is loaded from a local CSV file via `d3.csv`, with each row parsed into a `Date` object and numeric user count, then rendered as SVG paths and circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/212ebe03fd104c33982edc5973917332?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
