This visualization displays a correlation matrix of clinical indicators related to heart disease, using a diverging color scale to highlight positive and negative relationships. It shows the computed Pearson correlation coefficients between seven numeric variables, with values printed within each cell. Built with React and D3 v7, the code uses `scaleLinear` to map correlations to colors, calculates correlations manually, and renders the matrix as SVG rectangles with interactive hover highlighting.

Correlation_Matrix

This visualization displays a correlation matrix for the Abalone dataset, showing pairwise Pearson correlation coefficients between physical measurements and age. Across the main diagonal, variable names are labeled, while off-diagonal cells use either colored text or circles with varying radius and color intensity to represent correlation strength and direction. The matrix is filtered by selecting a categorical variable (Male, Female, or Infant) from a dropdown menu, which recomputes correlations for that subset. Built with D3 v7 in React, the code uses `d3.scaleLinear` for color encoding, `d3.scalePoint` for axes, and `d3.scaleSqrt` for circle sizing, rendering to SVG.

Correlation Matrix

This visualization displays a correlation matrix for 26 randomly generated variables, where each cell’s color indicates the correlation strength between two variables. The data is synthesized with random numbers, and the matrix reveals that most correlations are near zero, with only the diagonal showing perfect correlation. The implementation computes correlations using jeezy's `correlationMatrix` function, arranges the cells with data2grid, and maps colors with a chroma scale from tomato through white to steelblue. D3 v4 renders the SVG grid, while hover interactions highlight corresponding rows, columns, and a tooltip showing the exact correlation value.

Correlation Matrix

This visualization displays a correlation matrix for 26 randomly generated variables (columns a through z), with each cell’s color indicating the correlation strength between variable pairs. The heatmap uses a red-white-blue color scale, and hovering over a cell highlights the corresponding row and column labels while showing the exact correlation value in a tooltip. The example computes the correlation matrix with jeezy's correlationMatrix function, arranges the cells using data2grid, and renders them as SVG rectangles with d3.v4. Chroma.js generates the color scale, and the visualization includes animated opacity transitions and interactive hover effects.

Correlation matrix

This visualization shows a correlation matrix for the Abalone dataset, displaying the relationships between eight physical measurements and age rings. The matrix uses colored rectangles, with a tomato-to-steelblue color scale via chroma-js, to represent correlation values between variable pairs. Built with React and D3 v4, the code uses `jz.arr.correlationMatrix` to compute correlations and `data2grid.grid` to structure the data. Hovering over a rectangle highlights the corresponding row and column labels while displaying the exact correlation coefficient in a tooltip.

Visualizing correlations between heart disease patients' data

This interactive scatter plot lets users explore correlations among heart disease patients by selecting any two metrics from dropdown menus, which map to the x- and y-axes. Each point represents a patient, colored by heart disease status, from a CSV dataset. Built with D3 v7, it uses scaleLinear, axisBottom, axisLeft, and transition().delay().duration() for animated point placement. The chart renders in SVG with adjustable margins and axis labels.

Correlation Matrix

This correlation matrix visualizes the relationships between 26 random variables (columns a–z) across 31 data points, using a color scale from tomato to steelblue to represent correlation strength, ignoring perfect self-correlations. Built with D3 v4 and the jeezy and data2grid libraries, the grid renders as an SVG with smooth opacity transitions. Users can hover over any cell to see the exact correlation value in a tooltip, while the corresponding row and column labels highlight in bold green to clarify the pair. The axes display the variable names along both dimensions, and the color scale uses a diverging white midpoint to emphasize positive versus negative correlations.

109550187_HW3

This visualization displays three correlation matrices for subsets of the Abalone dataset, showing the pairwise relationships between nine physical measurements. Each matrix uses diverging colors from blue through yellow to red to represent correlations from -1 to 1, with numeric values overlaid on each cell. A fourth SVG shows the corresponding color legend. The matrices are rendered as SVG using D3 v5 scales and the `jz.arr.correlationMatrix` API from the jeezy library, with interactive hover effects that display detailed correlation information in text below. The data is loaded asynchronously from a remote CSV file.

Correlation Matrix

This visualization presents a correlation matrix for the Abalone dataset, split into three separate SVG grids for male, female, and infant samples. Each cell color encodes the correlation coefficient between two variables, using a red-to-white-to-steelblue Chroma.js scale. Hovering over a cell highlights the corresponding row and column axis labels and displays the exact correlation value in a tooltip. The implementation uses D3 v4 scales and axes, the `jz.arr.correlationMatrix` function from the jeezy library for computation, and `data2grid` for grid layout.
