{"version":"1.0","type":"rich","title":"Bar Chart Practice","description":"This bar chart displays the average energy price in euros per megawatt-hour for four seasons in Spain from 2015 to 2018, sourced from a Kaggle dataset. It shows a fall peak above 64, with spring lowest near 51. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map prices to horizontal bar lengths and seasons to vertical bands. SVG rectangles render the bars with steelblue fills, with margins and axes configured in a single group element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a70472f0694243fcb0e47a2deebbbb40?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
