This example shows a set of five circles arranged diagonally across a responsive SVG canvas. Clicking any circle toggles its state, changing its fill from black to white and adding a thick black outline. The visualization uses React state to track the selected circle and D3 v7 scales to map fixed data coordinates to the container’s dynamic width and height. A ResizeObserver hook measures the container, triggering a re-render of the circles via D3’s select and join pattern.

CV: Clickable Circles

A React application renders five black circles positioned along a downward curve using D3.js. Clicking any circle turns it white with a black outline, visually indicating selection through a state-managed callback. The visualization leverages D3's `select` and `join` operations within an SVG container, with circle coordinates and styling defined directly in the data array and rendered through `renderCircles`. The selected state is tracked in React and re-applied on each interaction.

Fork of CV: Clickable Circles

This example shows a set of five circles arranged diagonally across an SVG canvas. Clicking a circle toggles its fill to white with a black stroke, while all others remain black, using React state to track the selected circle’s ID. The visualization is rendered with D3 v7, where select and join manage circle elements, and the click handler updates React state via a callback.

Clickable Circles with D3 and React

Clickable circles rendered in an SVG canvas demonstrate a React and D3 integration. The visualization shows 14 circles with varied positions, sizes, and colors from a static array. Clicking a circle selects it, highlighting its outline with a black stroke. The App component manages selection state and re-renders the D3 visualization via `select()` and `.join()` for efficient DOM updates. The `viz` function uses D3’s SVG selection API to set attributes and attach click handlers, while React’s `useState` and `useEffect` control the interactive response.

Clickable Circles with D3 and React

A grid of pastel-colored circles, each positioned by explicit pixel coordinates from a static data array, fills the visualization. React manages the application state while D3's `select` and `join` methods render the SVG `<circle>` elements. Hovering a circle triggers a `mouseover` event that calls `setSelectedId`, updating React state and re-running the D3 selection to draw a black stroke around the active circle, while `mouseout` clears the highlight.

Clickable Circles

This example demonstrates interactive selection of circles rendered with D3.js. Each circle displays its own position and radius, and clicking one highlights it with a black stroke and raises it above the others. The visualization uses a unidirectional data flow pattern where state changes trigger re-rendering through the `viz` function. D3’s `selectAll` and `join` methods manage circle creation and updates, while click event listeners call `setSelectedDatum` to update the selected circle’s styling.

HAW test 5.12

Five circles, positioned proportionally from a CSV file, are plotted on a responsive SVG canvas. Clicking a circle changes its fill to white with a black stroke while others remain solid black. Built with React and d3.v7, the visualization uses `scaleLinear` to map x and y coordinates from data space to the container's pixel dimensions, dynamically resizing via a `ResizeObserver`. The `join` API efficiently updates circle attributes and click handlers.

Circles with D3 and React

The visualization displays fourteen circles of varying radii and colors positioned across a 960-by-500 SVG canvas, with each circle’s center, size, and fill defined by a static array of objects. Built with React 19 and D3 v7, the app uses a `useRef` hook to select the SVG element and applies a D3 `select` and `.join` operation to bind the data array to circle elements. The code sets each circle’s `cx`, `cy`, `r`, and `fill` attributes directly from the data source, showing a straightforward declarative mapping of data to SVG shapes.

Clickable Circles from CSV

This example displays a set of colored circles loaded from a CSV file, each positioned and sized by its own coordinates and radius. Hovering over a circle highlights it with a black stroke, using a React state to track the selected circle's ID. The visualization is rendered with D3 v7's `select` and `csv` APIs, alongside React's `useEffect` and `useState` hooks, with circle attributes and mouse events applied via `selection.join`.
