{"version":"1.0","type":"rich","title":"Simple graph with grid lines in v4","description":"A simple line graph displays six date–value pairs from a local CSV file, with light grey horizontal grid lines extending across the plot. The visualization uses d3.v4 with SVG rendering, employing `d3.scaleTime` for the x-axis and `d3.scaleLinear` for the y-axis. The grid is generated by `d3.axisLeft` with custom tick sizing, while the line is drawn via `d3.line`. Axes are added using `d3.axisBottom` and `d3.axisLeft`, with x-axis tick values explicitly set to the data dates.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2b5af0db18bcd0cc94629524ab209dce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
