A scatterplot animates the transition of individual data points between two quantitative axes, plotting GPA against height. The D3.js code uses a single shared transition (`t`) to coordinate exit, update, and enter selections, moving circles vertically while fading opacity. Entering circles appear grey and semi-transparent at the baseline before transitioning to full opacity at their target height, while exiting circles fade back down. The animation relies on D3's data join and `transition` API to smoothly interpolate circle positions and opacity.

A scatterplot of student grade point averages against heights flickers between two datasets every second, swapping the points to show how the axes rescale to fit the new data. Built with D3.js, the visualization uses `d3.scaleLinear` to map the domains, `d3.axisBottom` and `d3.axisLeft` for the axes, and a `d3.interval` timer to trigger the update. The `update` function reuses existing circles via `enter` and `exit` selections, appending new ones with a radius of 5 and filling them grey.

A scatterplot maps student GPA on the x-axis against height on the y-axis, using D3.js to render circles with a fixed radius of 5 pixels and grey fill. The code binds data to circle elements via `d3.select("#canvas").selectAll("circle")`, then appends new circles with `.enter()` and positions them using the scale functions `x(d.gpa)` and `y(d.height)`. The example demonstrates basic SVG circle creation from an array of data objects, with no axes or interactivity shown.

An animated scatterplot uses D3.js transitions to update its x- and y-axes. The code calls `xAxis.transition(t).call(xAxisCall)` and the equivalent for the y-axis, smoothly interpolating the axis scales over time. The data points themselves are not explicitly rendered in this snippet, but the focus is on the axis transitions that accompany the underlying data updates. The visualization relies on D3’s selection and transition APIs to coordinate the animation, presenting a dynamic view of changing relationships between two variables.

A scatterplot drawn on an HTML canvas displays each record from a dataset as a grey circle, with horizontal position mapped to GPA and vertical position mapped to height. The code uses D3.js to select the canvas element and append circle elements for every item in the `data0` array, setting their `cx` and `cy` attributes accordingly. The visualization shows the distribution of GPA against height, with a fixed radius of 5 pixels for all points.

This example demonstrates how D3.js handles data joins by updating circles on a scatterplot, where each circle’s position is mapped from GPA and height values. New data elements enter the visualization as small grey circles, appended via `circles.enter().append("circle")`, with their horizontal and vertical coordinates set using the `x` and `y` scale functions. The code explicitly assigns the circle’s radius to 5 pixels and fill color to grey, showing a basic static rendering of newly added points without transition or animation.

Two small scatterplots compare GPA against height for two separate student groups, using circles positioned by Cartesian coordinates. The code loads data arrays with six and nine points respectively, then renders them with D3.js, likely via `d3.forceSimulation` for layout or a standard scale-based plot. Each dot encodes the paired numerical values, and the minimal styling keeps focus on the distribution difference between the datasets, though no axes or labels are drawn in the provided snippets.

This scatterplot shows the relationship between grade point average and height in centimeters, with each point representing an individual. The visualization uses D3.js to render the axes, employing `d3.axisBottom` for the x-axis and `d3.axisLeft` for the y-axis. Axis labels are appended directly to the axis groups, with the x-axis titled "Grade Point Average" and the y-axis rotated to read "Height / Centimeters." The data is plotted against these quantitative scales, though the underlying dataset is not visible in the code excerpt.

D3 Scatterplot (Animations)

This D3 scatterplot demonstrates animated transitions between datasets. The visualization initially renders 15 random data points as circles, with x- and y-axes scaled to the data’s domain. When a user clicks the text header, new random data replaces the old, and the circles smoothly transition to their updated positions while the axes rescale accordingly. The code uses d3.svg.axis for the axes and d3.selectAll("circle").transition() to animate the updates, with scales from d3.scale.linear.
