This interactive D3 v4 heatmap displays a two-dimensional histogram of date and value buckets, with tile colors encoding count data. Users select from a menu of sequential color interpolators, including Viridis, Inferno, and colorbrewer schemes, to recolor the visualization. The chart updates dynamically using `d3.scaleSequential`, and an animation cycles through interpolators every second until manual selection. The SVG rendering includes axes, a color legend, and labels for the count, date, and value dimensions.

An upgrade of <a href='http://bl.ocks.org/mbostock/'>mbostock</a>'s block: <a href='http://bl.ocks.org/mbostock/3202354'>Heatmap (2D Histogram, CSV)</a> to D3 4.0, with the addition of a select menu for D3 Sequential Scale Interpolators. Inspired by d3-scale issue: sequential.interpolate? #67. Draws the idea of trying out color schemes from colorbrewer2.org.

Also includes scales from d3-scale-chromatic.

D3 4.0 Sequential Scales Explorer

This interactive heatmap visualizes a 2D histogram of date and value data, with cell colors encoding counts. A dropdown menu and auto-cycling animation let users switch among sequential color interpolators from D3 4.0’s `d3.scaleSequential` and the `d3-scale-chromatic` library, including Viridis, Inferno, and ColorBrewer schemes. Built with D3 4.0, it renders SVG rects and axes, loading data from a CSV file.

4.0 Color Scales - Sequential

This example showcases 27 sequential color scales, comparing those built into D3 v4 with those from the d3-scale-chromatic library. The visualization renders a full-width set of thin vertical bars, initially colored using the Inferno scale, with each bar’s fill mapped to its x-position via a `d3.scaleSequential` interpolator. Clicking a button above the chart triggers a transition that smoothly recolors the bars using the selected interpolator, such as Viridis, Blues, or YlGnBu. The interface uses SVG rectangles and D3’s transition API for animated updates, with the code leveraging `d3.range` and data-driven styling.

Untitled

This interactive heatmap displays hourly activity counts for each date, using a color gradient to show intensity variations. The visualization renders a grid of tiles positioned by date and hour bucket, with color encoding count values via a sequential scale. It cycles through multiple color interpolators automatically, including Viridis, Inferno, and sequential schemes from d3-scale-chromatic, while allowing manual selection. The code uses d3.csv for data loading, d3.scaleTime, d3.scaleLinear, and d3.scaleSequential to map values, with SVG rectangles and d3.axisBottom/d3.axisLeft for the chart’s axes.

D3 Scale - ScaleSequential - Different Interpolators

This example demonstrates eight different D3 color interpolators applied to sequential scales, each rendered as a horizontal band of colored rectangles. The visualization shows how the viridis, inferno, magma, plasma, warm, cool, rainbow, and cubehelixDefault colormaps transition across a 0–100 domain, with each interpolator labeled above its corresponding row. The code uses `d3.scaleSequential()` with each interpolator to map data values to fill colors, while `d3.scaleLinear()` positions the rectangles along the x-axis. The SVG output is generated from range data via `d3.range()` and rendered with D3's data join pattern.

Heatmap

A d3.js heatmap displays a matrix of values using the Inferno color scale, with each cell representing a combination of a group and variable from a CSV dataset loaded from GitHub. The SVG rendering includes band scales for axes, rounded rectangles, and a tooltip that shows the exact value on hover. The code uses d3.scaleSequential with d3.interpolateInferno, d3.axisBottom, d3.axisLeft, and mouse event handlers for interactivity.

Heat Map

This heat map visualizes a sequential color scale transitioning from purple to orange across a continuous spectrum. The view fills the browser window with 100 vertical rectangular bands, each colored via the `d3.scaleSequential` interpolator. The code uses `d3.interpolate` to blend the two colors, `d3.scaleLinear` for positioning, and SVG `<rect>` elements rendered with D3 v7. The example demonstrates how to construct a full-viewport gradient bar for quantitative data mapping.

Day / Hour Heatmap in v4

This heatmap visualizes concurrent user sessions across days of the week and hours of the day, with cell color intensity encoding the session count. The SVG-based chart uses `d3.scaleQuantile` with a nine-color YlGnBu palette and includes a legend showing quantile thresholds. It reads TSV data via `d3.tsv`, renders labeled day and hour axes, and animates color transitions with `transition().duration(1000)` when switching between two datasets using the dataset picker buttons.

A6 - Color Scales in D3

This example demonstrates four distinct D3.js visualizations, each employing a different color scale type: a bar chart using a sequential color scale, a diverging bar chart with a diverging scale, a scatterplot with a qualitative scale, and a line chart. The code uses D3’s `scaleSequential`, `scaleDiverging`, and `scaleOrdinal` APIs to map data values to colors. Each chart is rendered using SVG elements created via D3’s `select` and `append` methods. The visualizations are embedded as standalone pages, with the bar chart and diverging chart showing categorical comparisons, while the scatterplot and line chart reveal patterns across continuous variables.
