{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example visualizes weekly U.S. gasoline prices as a line chart, with time on the x-axis and price per gallon on the y-axis, emphasizing trends through a simplified, clean design. It uses the Vega-Lite API to construct the chart declaratively, registering it with Vega and Vega-Lite, while D3’s `csv` module is referenced for potential data loading. The data, a static array of timestamped prices, is passed directly to the chart, which renders as a full-window SVG. Custom axis styling and large label fonts are configured to improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6eaf5b0cf1d149c993e5b13143c31185?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
