{"version":"1.0","type":"rich","title":"Jednoduchy Pie chart","description":"This example shows a simple pie chart built with D3.js v4, displaying eight data values as proportional arcs in a 450-by-450 pixel square. The chart uses `d3.pie()` to compute the arc angles from a hard-coded JavaScript array, with no external data file. The rendering relies on the `d3` library’s default arc generator, though the code defines only the pie layout and dimensions without explicit SVG path creation. Styling comes from a linked stylesheet that sets steelblue fill for rectangles and sans-serif text, while the page loads the D3 script from a CDN. The visualization is static, with no interactions or transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ba4000d4bb844f490619c30e808db9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
