A brushable scatterplot matrix displays pairwise relationships among four Iris flower measurements (sepal length, sepal width, petal length, petal width) from the classic Iris dataset. Users drag a brush rectangle over any scatterplot cell to highlight corresponding points across all other cells, while unselected points dim. Diagonal cells show histograms of each measurement. The visualization uses D3 v7 with `d3.scaleLinear` axes, `d3.brush` for interactive selection, and SVG rendering; three Iris species are color-coded with distinct hex values.

Fork of HW4 Brushable Scatterplot Matrix

This interactive scatterplot matrix visualizes the Iris dataset, displaying pairwise relationships between sepal and petal measurements across all combinations. Each off-diagonal cell shows a scatterplot of points colored by species, while diagonal cells display histograms of individual variables. Users can brush selections within any scatterplot cell to highlight corresponding points across all other cells simultaneously, with brushed points remaining visible while others fade to gray. The visualization uses D3 v7 with SVG rendering, employing `d3.brush()` for interactive selection, `d3.scaleLinear()` for axes, and `d3.bin()` to generate histograms.

Brushable Scatter Plot Matrix

This interactive scatter plot matrix visualizes the Iris dataset, showing pairwise relationships between four flower measurements—sepal length, sepal width, petal length, and petal width—with points colored by species. Using d3.brush, users can drag across any off-diagonal cell to filter and highlight points across all other cells simultaneously, while diagonal cells display histograms of each variable's distribution. The visualization is built with d3.v4, rendering axes and circles as SVG elements, with scales derived from the CSV data's numeric ranges.

HW04-Brushable Scatter Plot Matrix

A brushable scatter plot matrix displays pairwise relationships among four measurements of the iris dataset, with histograms along the diagonal and colored scatter plots for each trait combination by species. Users can drag a rectangular brush across any cell to select data points, which highlights matching points across all other cells. Built with D3 v4, the visualization renders as SVG and uses `d3.brush`, `d3.scaleLinear`, `d3.scaleOrdinal` with `d3.schemeCategory10`, and `d3.histogram` for the diagonal distributions. The axes are generated via `d3.axisBottom` and `d3.axisLeft`.

Brushable Scatterplot

This interactive scatterplot matrix displays the Iris dataset, showing pairwise relationships between four floral measurements. Each off-diagonal cell contains a scatterplot of data points colored by species, while diagonal cells display histograms of individual feature distributions. Users can brush rectangular regions across any plot to highlight corresponding points in all other cells, enabling rapid comparison of multi-dimensional correlations. The visualization is built with D3 v4, using d3.brush for the linked selections, d3.scaleLinear for axes, and d3.axisBottom/Left for tick marks, rendered as SVG.

Fork of HW04-Brushable Scatter Plot Matrix

This visualization is a brushable scatter plot matrix of the Iris dataset, showing pairwise relationships between sepal and petal measurements. Each off-diagonal cell displays colored scatter points by iris species, while diagonal cells show histograms of individual trait distributions. Users can brush over any cell to highlight corresponding points across all other plots. The code uses D3 v4 with SVG rendering, employing `d3.brush`, `d3.histogram`, `d3.scaleLinear`, and `d3.scaleOrdinal` to generate the interactive matrix. Data is loaded from a local CSV file.

Fork of HW04-Brushable Scatter Plot Matrix

This example is a brushable scatter plot matrix of the Iris dataset, showing pairwise relationships between sepal and petal measurements with points colored by species. The matrix features histograms along the diagonal and scatter plots in off-diagonal cells, where users can brush to highlight selections across all panels. Built with D3 v4 and SVG, it uses `d3.brush()` for interactive brushing, `d3.scaleLinear` and `d3.scalePoint` for positioning, and `d3.histogram()` to bin data for the diagonal distributions. The visualization is derived from the classic brushable scatter plot matrix example, adapted to include per-cell axes and histograms.

Brushable Scatter Plot Matrix

A brushable scatter plot matrix displays pairwise relationships among four numeric iris flower measurements, with histograms along the diagonal showing each variable's distribution and points colored by species. The visualization is built using D3 v7, rendering SVG elements via `d3.csv` for data loading, `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.histogram` for binning the diagonal distributions. Each off-diagonal cell encodes two variables as a scatterplot, while the color scale uses `d3.scaleOrdinal` with `d3.schemeCategory10` to distinguish Iris species.
