{"version":"1.0","type":"rich","title":"28. D3 Bar Chart Blues","description":"A bar chart displays a fixed dataset of 20 numeric values in a viewport 500 pixels wide and 100 pixels high. Each bar’s height is proportional to the data value, scaled by a factor of four, and its horizontal position is computed from the array index and overall width. The bars are rendered as SVG rectangles using the D3.js v4.5.0 library, with a dynamic fill color that transitions from dark to lighter blue based on the data value. This example demonstrates simple data-driven styling without any animation or interactive elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/254c134f690e4c7d918b8fe0b77bb99f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
