This visualization presents a brushable scatter plot matrix of the classic Iris dataset, showing pairwise relationships between four floral measurements across 150 flowers. Users can brush points in any scatter plot pane to highlight selections, which are then reflected in all other panels and as color-coded, stacked histograms along the diagonal. The chart is built with D3 v7, using `d3.brush` for interactive selection, `d3.scalePoint` for panel positioning, and SVG elements for all rendering. Each flower is colored by its species using an ordinal scale, with unselected points rendered in black.

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.

Brushable scatterplot2

This interactive scatterplot matrix displays the iris dataset, showing pairwise relationships between four flower measurements (sepal and petal length and width) alongside histograms on the diagonal. The visualization uses d3.csv to load the data and d3.scaleLinear with d3.axisBottom and d3.axisLeft for axes. Points are colored by species using d3.scaleOrdinal, with colors distinguishing setosa, versicolor, and virginica. The chart is built entirely with SVG, and while brushable functionality is mentioned in the title, the code shown does not implement brushing interactions.

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.

Fork of Brushable scattered plot

A brushable scatter plot matrix of the classic Iris flower dataset, rendered in SVG with D3 v7. The four measured features are paired across all combinations, showing categorical color-coded points for the three species. Brushing a region in any scatter plot filters the data across the entire matrix, updating the diagonal histograms to reflect the selected subset with species-specific stacked colors. The visualization uses `d3.scalePoint`, `d3.scaleLinear`, and `d3.brush` to coordinate interactions.

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.

Fork of Fork of Brushable Scatterplot

This brushable scatterplot matrix displays the classic Iris flower dataset, showing how four sepal and petal measurements relate to three iris species. Each cell in the grid plots one measurement pair, with points colored red, yellow, or blue by species. Users can drag a brush across any cell to highlight corresponding data points across all other scatterplots, with brushed points remaining colored while unselected points turn gray. The visualization uses D3 version 3 APIs including `d3.svg.brush()` for the interactive brushing, `d3.scale.linear()` for axes, and coordinates rendered as SVG circles.

HW4 Brushable Scatterplot Matrix

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.
