{"version":"1.0","type":"rich","title":"Composition of dry air at sea level","description":"This visualization presents the volume percentage composition of dry air at sea level, using a bar chart to display the relative abundance of each gas, from nitrogen and oxygen to trace gases. The chart is built with D3.js version 3 and uses an ordinal scale for the categorical x-axis and a linear scale for the y-axis, which is formatted to show percentages. Bars are rendered as SVG rectangles, and hovering over a bar or its associated tick label reveals a tooltip with the substance’s name, volume percentage, and concentration in ppmv. The data is loaded from a CSV file and is based on values from a physical chemistry textbook by Atkins and de Paula.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/648a73abbfcb4c059ed6013644b7dd3a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
