Clicking the update button regenerates a random dataset and redraws a row of circles across an SVG chart. Each circle’s radius and fill color encode its numeric value, with values above 30 turning orange and others light gray. The example uses D3 v7’s data join pattern (`selectAll`, `data`, `join`) to create and update circle elements, driven by a simple JavaScript function that generates random data counts and sizes.

Learn D3 1

This example demonstrates how D3's data join pattern updates circle elements in an SVG as the dataset changes. It first binds an array of two numbers to render a row of circles, then reuses the same selection with a longer array of five numbers, causing the existing circles to update and new ones to enter. The visualization uses the `join()` method in D3 v7 with the `selectAll` and `data` APIs, setting each circle's position via the `cx` attribute based on its bound value. The code runs within a simple container using `select` and creates a fixed 980 by 500 SVG canvas.

Untitled

This example demonstrates D3's enter, update, and exit selections in a data join, showing how circles are added, recolored, or removed as the dataset changes with each button click. Clicking the Update button generates a random number of items (each with value 40) and renders them as blue circles on entry, red on update, and green on exit. The code uses d3.select and selectAll with the .join() method, including explicit enter, update, and exit functions, and applies attributes for positioning and radius via .attr(). The SVG rendering is handled in a 960×100 viewport.

d3 selection

This example demonstrates D3’s data join and update pattern through an animated swarm of purple circles. It shows how circular marks continuously reposition and resize based on a periodic mathematical function. The visualization uses D3 v7’s `select` and `range` to generate data, appends an SVG to the body, and updates circles every 100/60 milliseconds via `setInterval`. The `.join('circle')` method handles enter and update selections, binding new data arrays while styling radius, x/y coordinates, and fill.

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.

D3 Practice

This example demonstrates how D3’s data join handles changing datasets, showing circles rendered from an array of five random integers. After drawing all circles, the code trims the data to three items, and the exit selection removes the extra circles from the SVG. It uses React 16.13 and D3 v6, with the `d3.randomInt` generator supplying values and D3’s selection methods (`data`, `enter`, `exit`) managing circle updates. The SVG is appended directly to the body, with no interactive behavior beyond the static removal.

Changing data

Two datasets of varying circle sizes and counts are displayed along a horizontal axis. A button click uses `d3.select` and event listeners to toggle between datasets, demonstrating D3’s data join pattern with `data()`, `enter()`, and `exit()`. New circles appear via `append` with an initial radius of zero, while all circles transition with `transition().duration(500)` to update their `cx` and `r` attributes, and the dataset label changes via `select("text").text()`. The SVG elements are rendered as orange, semi-transparent circles.

transition in d3

This example demonstrates how to update circle positions in an SVG using D3 transitions. Clicking the button generates five random data values with a JavaScript loop and applies them to the circles via the `data()` join method. The code uses D3 v7’s `select` and `selectAll` functions, along with the `join` method to bind data and update the `cx` attribute, though no explicit transition is defined. The visualization relies on a simple SVG container with hardcoded circle elements and a randomized numeric dataset.

D3 Data Loading...

This example creates a single red circle within an SVG canvas that dynamically tracks the mouse position, using mousemove events to update its center coordinates. Clicking anywhere on the canvas triggers a random RGB color change, altering the circle’s fill. The visualization utilizes d3.select and the join method to efficiently create and update the SVG and circle elements, while managing a state object that stores the current x, y coordinates and color. The viewport dimensions are set to match the browser window size.
