{"version":"1.0","type":"rich","title":"Multi Chart","description":"This visualization uses four linked scatter plots to explore an MRI and Alzheimer’s dataset. It shows relationships between brain volume, dementia severity, age, education, and gender, highlighting that dementia correlates with lower normalized brain volume and occurs more in older populations. The plots are built with the vega-lite-api and rendered using vega-lite, with data loaded via d3.csv from a Gist. Each plot encodes variables through position, color, and size channels, with tooltips provided by vega-tooltip. The data originates from the Open Access Series of Imaging Studies (OASIS).","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63c2a3c24e6d431a855529a3cd24780d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
