{"version":"1.0","type":"rich","title":"activity 6_question 4","description":"This bubble chart displays daily weather observations from a climate dataset, plotting humidity on the x-axis against mean pressure on the y-axis. Each circle’s radius encodes wind speed, while its color represents mean temperature, using a viridis sequential color scale. The visualization is built with D3 v7, using `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble sizing, and `d3.scaleSequential` for color mapping. A legend with a linear gradient and axis communicates the temperature scale, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7dd9d7f3fee54a7cba2e4bf27952e11e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
