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.

This example shows how D3.js updates existing circle elements when the underlying dataset changes. The visualization binds new data to previously rendered circles, then repositions them by setting their `cx` and `cy` attributes through the `x` and `y` scale functions, which map `gpa` and `height` values to screen coordinates. Using the data join pattern, the code explicitly targets old elements present in the new data array. The scales are defined elsewhere, but the update logic relies on D3’s selection and attribute methods to reflect the changed data without recreating the entire scene.

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.

This example demonstrates a basic data join with D3.js, showing how circles are appended to an SVG canvas based on an array of data. The visualization displays five grey circles positioned diagonally, with each circle’s x and y coordinates calculated from its index in the data array. The code uses D3’s `selectAll` and `data` methods to bind data to circle elements, followed by `enter().append()` to create new circles with fixed radius and fill color. The rendering approach is declarative, relying on D3’s data-join pattern rather than explicit loops.

This example demonstrates a data-join update pattern for circles in a D3.js visualization. It shows how existing SVG circle elements are bound to a new dataset using `g.selectAll("circle").data(data)`, a core D3 concept that prepares the scene for entering, updating, or exiting elements. The code uses the D3 selection API to join the new data with the old elements, making it a foundational step for dynamic transitions or rescaling. The visualization itself is not yet animated or interactive—it only establishes the data binding, leaving subsequent update logic (such as position or radius changes) out of the visible snippet.

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.

d3 circles

This example displays a scatterplot of 50 randomly generated data points, each positioned by x and y coordinates on linear scales. The circles transition from teal to black with varying radii based on the y-value. Clicking the prompt above the chart generates new data points, triggering animated transitions that update circle positions, radii, and the axes using d3.axisBottom and d3.axisLeft. The visualization uses d3.v4 with SVG rendering, including a clipPath to contain the circles within the chart area.

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.

Fork of Circles with D3

This example shows a simple scatterplot of circles arranged on a 2D plane, with each circle’s position and size determined by explicit data values. It demonstrates D3’s data join and method chaining to bind an array of circle objects to SVG `<circle>` elements, setting `cx`, `cy`, `r`, and `fill` attributes. The visualization uses D3 v7 with the `select` function and the `.data().join()` pattern for efficient rendering, while the canvas background and opacity styling enhance the overlap effect. Data is embedded directly in the code as a static array, serving as a foundation for later loading external data sources.
