A scatterplot displays the relationship between normalized brain volume (nWBV) and estimated total intracranial volume (eTIV) for individual patients from the OASIS cross-sectional MRI dataset. Circles encode education level by size and sex by color, with tooltips revealing the atlas scaling factor. The visualization uses the vega-lite-api to construct the chart, d3.csv for data loading, and vega-tooltip for interactivity, with a custom configuration adjusting axis and label styling.

AI-generated description

A visualization constructed using the vega-lite-api.

In this MIR and Alzheimers dataset, we mainly look at the data table in file: oasis_cross-sectional01.csv

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

See Data on Gist: MRI and Alzheimers

The original data comes from the Open Access Series of Imaging Studies (OASIS)

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.

MRI and Alzheimers Data

This visualization explores the OASIS MRI dataset across four linked scatter plots, revealing relationships between brain volume, dementia severity (CDR), age, education, and gender. It shows that dementia correlates with smaller normalized brain volume, occurs primarily in older patients, and that eTIV and ASF exhibit a nonlinear inverse relationship, while gender shows clear separation in eTIV. Built with the vega-lite-api library and rendered via Vega-Lite, the plots use circle marks with color, size, and tooltip channels, pulling data from a CSV file and displaying charts in a 2x2 grid.

MRI and Alzheimers Data

This gallery page presents four scatter plots exploring the relationship between brain measurements and dementia in the OASIS MRI dataset. The visualizations show that dementia corresponds to lower normalized brain volume, that eTIV and ASF share a fixed non-linear inverse relationship, and that dementia occurs more frequently in older populations without a clear link to education. Plots colored by gender reveal a separation in eTIV values. Built with the Vega-Lite API and D3.js, the code uses `vl.markCircle` encodings for position, color, and size, pulling data from a CSV file via `d3.csv`.

Fork of MRI and Alzheimers Data

This visualization explores an MRI and Alzheimer’s dataset from OASIS, presenting four scatter plots that examine relationships between brain volume, dementia severity (CDR), age, education, and gender. It uses the vega-lite-api and d3.csv to load and render the data. The plots reveal that dementia correlates with lower normalized brain volume, eTIV and ASF share an inverse nonlinear relationship, and gender differences appear in estimated intracranial volume. The charts leverage Vega-Lite’s markCircle encoding, with color and size channels, and include custom axis styling via a config object.

Multi Chart

This multi-chart visualization explores the OASIS MRI and Alzheimer’s dataset, showing relationships between brain volume, dementia status, education, age, and gender. Four scatter plots juxtapose variables like normalized brain volume (nWBV) and estimated total intracranial volume (eTIV), with color and size encoding categorical and ordinal fields. The charts are constructed using the vega-lite-api, which wraps Vega-Lite and Vega, rendering SVG via a view configured with a tooltip handler. Data is loaded from a CSV URL using d3.csv.

Multi Chart

This multi-chart visualization explores an MRI and Alzheimer’s dataset from OASIS, using four scatter plots to examine relationships between brain volume, dementia severity, education, age, and gender. Each plot encodes variables through position, color, and size, highlighting patterns such as the inverse relationship between estimated total intracranial volume and atlas scaling factor, and the association of dementia with older age and lower brain volume. Built with the vega-lite-api on D3 v5, the charts render as SVG and include interactive tooltips via vega-tooltip, with data loaded from a CSV file.

MRI and Alzheimers Data

This example loads two MRI datasets from the OASIS study using the Fetch API and `d3.csv`, then reports basic file statistics for each. It displays the filename, size in kilobytes, row count, and column count as plain text in a `<pre>` element. The visualization is minimal, focusing on data loading and validation rather than graphical rendering. Both cross-sectional and longitudinal CSV files are fetched asynchronously with `async/await`, and results are appended to the page via `textContent`.
