This contour plot visualizes the Old Faithful dataset, showing the density of eruptions against waiting times as a smooth gradient of green-filled polygons. The code uses d3-contour’s `d3.contourDensity` to compute density estimates from the scatter data, and d3-scale-chromatic’s `interpolateGreens` for the sequential color scale. SVG rendering via D3 v4 draws the contours with `d3.geoPath`. An interactive mouse move adjusts the bandwidth of the density estimation from zero to forty, updating the plot in real time.

Old Faithful Contour Plot B

This visualization displays the Old Faithful geyser dataset as a smooth contour plot, with eruption time on the x-axis and waiting time on the y-axis. The code uses d3.contourDensity to compute density contours from the data, then renders them as filled SVG paths via d3.geoPath, with a sequential color scale from d3-scale-chromatic using interpolateGreens. Interactive bandwidth adjustment occurs on mousemove, altering the contour smoothing level dynamically. Axes are drawn using d3.axisBottom and d3.axisLeft, with data loaded via d3.tsv from a GitHub gist.

Old Faithful Contour Plot B - 2

This visualization shows the relationship between eruption time and waiting time for the Old Faithful geyser dataset, using density contours to highlight areas of high data concentration. The contours are computed with `d3.contourDensity` and rendered as SVG paths via `d3.geoPath`, with colors mapped through `d3.scaleSequential` and `d3.interpolateGreens`. The axes are drawn with `d3.axisBottom` and `d3.axisLeft`, and the contour bandwidth updates interactively based on mouse movement across the page, demonstrating dynamic resmoothing of the density estimate.

Fork of Old Faithful Contour Plot

This visualization shows the Old Faithful dataset as a contour plot, with eruption time on the x-axis and waiting time on the y-axis. The density of data points is represented through filled contour regions using a sequential green color scale. The code uses d3-contour’s `contourDensity` to compute the contours, and `d3.geoPath` to render them as SVG paths. Axes are drawn with d3.axisBottom and d3.axisLeft, and moving the mouse dynamically updates the bandwidth of the density estimation, recomputing the contours in real time.

Old Faithful Contour Plot

A contour plot visualizes the density of eruption data from the Old Faithful dataset, with continuous green-shaded regions representing higher concentrations of points. The visualization uses d3.contourDensity to compute density estimates and d3.geoPath for rendering the resulting contours as SVG paths. Axes and labels are drawn using d3.axisBottom and d3.axisLeft, while a sequential color scale with d3.interpolateGreens maps density values to fills. The interactive example updates the contour bandwidth dynamically as the mouse moves across the page.

Fork of Old Faithful Contour Plot

This interactive contour plot visualizes the Old Faithful dataset, showing the density of eruption and waiting times through colored bands. The visualization displays contours rendered as filled SVG paths using `d3.geoPath`, with colors mapped from a sequential greens scale. Users adjust the density bandwidth by moving their mouse across the plot, which triggers a re-render of the contour data via `d3.contourDensity` and `d3.select` event handling. Axes and labels are drawn using `d3.axisBottom` and `d3.axisLeft`, and the density estimate uses a Gaussian kernel with a bandwidth that ranges from 0 to 40 pixels as the mouse moves horizontally.

Density Contours

This example visualizes the density of the Old Faithful geyser dataset, showing the relationship between eruption duration and waiting time. It displays smooth contour lines that represent the estimated probability density of the data points, overlaid on a scatterplot of individual measurements. Built with D3 v4, the code uses `d3.contourDensity` to generate the contours and `d3.geoPath` to render them as SVG paths. The data is loaded from a TSV file, with axes labeled for idle and erupting minutes.

Old Faithful Contour Plot

This contour plot visualizes the density distribution of data points using a white-to-teal gradient, with darker regions indicating higher point concentrations. It reads data from a CSV file and displays it as smooth, layered density contours over a coordinate grid. The visualization uses d3.contourDensity to compute density values, d3.geoPath to render the contour shapes, and d3.scaleLinear for the color mapping. The axes are generated with d3.axisBottom and d3.axisLeft, and the data is plotted in an SVG canvas.

Old Faithful Scatter Plot

This scatter plot visualizes the Old Faithful dataset, showing the relationship between eruption time and waiting time. The visualization uses overlapping semi-transparent green circles to convey data density, with larger circles at lower opacity revealing concentrated clusters. Built with D3 v4, the code loads tab-separated data via `d3.tsv` and renders SVG circles with dynamically adjusted radii. The interactive component responds to mouse movement on the page, recalculating the circle radius based on cursor position to explore different density levels. Axes are styled with custom tick marks and labels using D3's axis components.
