This example presents a simple interactive D3.js v4 visualization of two sets of points. The interface displays three circles at distinct positions and radii, with two "Update" buttons that trigger a user-defined `updatePoints` function. The code creates an SVG canvas using `d3.select("body").append("svg")` and defines two point arrays (`points1` and `points2`) containing x, y, and radius values. Although the update function is currently empty, the structure demonstrates how to bind button clicks to replace or redraw the circular elements, serving as a minimal template for dynamic positional data updates.

circle dance

Two buttons trigger the animation of three red circles to new positions. The circles move between two predefined sets of coordinates over a two-second duration, demonstrating basic data updates in D3.js. The visualization uses D3 v4’s SVG rendering and the `transition()` method with a duration parameter to animate the changes. The code defines two data arrays containing `x`, `y`, and `r` properties for the circles, and the buttons call the `updatePoints` function to apply the new data.

circle dance end

Two buttons trigger the same animated update for a small set of circles, moving each circle’s center and radius to new values over two seconds. The visualization shows three red circles on an SVG canvas, with the animation smoothly interpolating their positions and sizes via D3’s `.transition()` and `.attr()` methods. The data consists of hardcoded JavaScript arrays of `x`, `y`, and `r` values, and the code uses D3 v4’s selection `.enter()`, `.merge()`, and `.transition().duration()` to handle the state change.

D3 functions

This example demonstrates D3’s data-join pattern with a set of circles plotted on an SVG canvas. Buttons trigger updates: “Remove” pops a data point, while “Modify” replaces a random point with new coordinates. Using `selectAll('circle')`, `enter`, `merge`, and `exit`, it shows how to handle entering, updating, and exiting elements. The code uses D3 v5’s `scaleLinear`, `select`, and `max`, with data defined as an array of `{x, y}` objects and rendering via SVG circles.

Example D3 functions

This example demonstrates the enter, update, and exit pattern for circle elements in D3 v5, using two buttons to modify an array of data points. The "Remove" button pops the last item, turning the exiting circle red, while the "Modify" button replaces a random entry, updating the circle’s position via `scaleLinear` mappings. The code imports `select`, `scaleLinear`, and `max` from D3, and uses SVG rendering with a fixed 960×500 canvas.

circles with D3

This example demonstrates the fundamental D3.js pattern of binding data to SVG circles. It uses `d3.select` to create circles, `d3.scaleLinear` to map data values to pixel positions, and `d3.axisBottom` to render an x-axis. The visualization shows how a simple dataset of numbers translates into a scatterplot, with circle radii scaled proportionally. The code highlights the step-by-step sequence of entering, updating, and exiting elements in a D3 data join.

D3 Selection Exploration (Enter - Update Selections Clearly Separated)

This example demonstrates the D3 enter-update pattern by animating a set of fifteen circles along a sine wave. Every five seconds, the data array is regenerated, and the code clearly separates the enter selection—which appends new circles with `circles.enter().append('circle')`—from the update selection that repositions existing elements via `circles.attr('cx', ...)` and `circles.attr('cy', ...)`. Using D3 v7 with SVG, the visualization shows how identical data keys map to existing nodes, avoiding duplication. The animation loops indefinitely using `setInterval`, and the rendering adjusts to the full browser window size.
