MRI and Alzheimers Data
This scatter plot explores the relationship between age, normalized brain volume (nWBV), and dementia severity (CDR) in the OASIS cross-sectional MRI dataset. Each point represents a patient, positioned by age and nWBV, with color encoding education level and point size indicating dementia rating. The visualization uses the vega-lite-api with d3.v5 for rendering, fetching data from a Gist-hosted CSV file. The chart is configured with custom styling for readability, including larger axis labels and a dark theme.

The important fields are:
- nWBV – Normalized Brain Volume
- CDR – Dementia
- Educ – Education
- M/F and Age – Patient info
- eTIV – Estimated Total Intracranial Volume
- ASF – Atlas Scaling Factor
