This visualization demonstrates a zoomable and pannable SVG canvas containing six colored circles of varying sizes and positions. The example uses the `d3-zoom` library's `zoom` function, which is applied to the SVG element to handle mouse interactions. A `transform` state, updated via a zoom event callback, is applied to a group element containing all circles, allowing the entire set to be panned and scaled smoothly. The circle data, including x, y, radius, and fill color, is hardcoded in the JavaScript.

Zoomable Circles with D3-Zoom

Six colored circles on a light green background form the focus of this example, which demonstrates how d3-zoom adds pan and zoom interactions. The visualization shows static circles positioned at fixed coordinates, with the zoom behavior updating a transform state that is applied to a group element. Dragging and scrolling the mouse translates and scales the entire circle collection smoothly. The implementation uses `d3.zoom` and binds its `zoom` event to update the group’s `transform` attribute, while the circle data remains unchanged, highlighting how the zoom layer operates independently of the underlying marks.

Fork of Zoomable Circles with D3-Zoom

This example presents a static scatterplot of six colored circles on a light green background, with zoom and pan interactions enabled. The circles are positioned at fixed coordinates and rendered as SVG elements using d3.select and attribute setters. The zoom behavior is implemented with d3.zoom, which captures the current transform in state and applies it to a group element containing all circles. The state-driven transform updates the group’s transform attribute, allowing the entire collection of circles to be moved and scaled smoothly.

Zooming and Panning

Four multicolored circles arranged in a square pattern sit at the center of an SVG canvas. The visualization demonstrates zooming and panning through d3.behavior.zoom, which captures mouse wheel drags and touch gestures. Users can scale the view between 1× and 10× magnification and pan freely by dragging. The circles’ positions are defined in data arrays and rendered as SVG circle elements with a translate transform applied to the parent group during zoom events.

Fork of Zoomable Circles with D3-Zoom

This example shows a set of six colored circles that can be panned and zoomed using the d3-zoom module. It uses the `select` and `zoom` functions from d3 to attach an interactive zoom behavior to an SVG container. The current transformation state, updated via `setState` on each zoom event, is applied to the group element holding the circles, which have fixed coordinates and radii. The visualization demonstrates how to integrate d3-zoom for panning and zooming within a VizHub environment.

Fork of Zoomable Circles with D3-Zoom

This example shows a zoomable bubble chart of six colored circles of varying sizes and positions. It demonstrates how to add pan and zoom interactions to a visualization using the D3.js library. The code uses `d3.zoom` to handle user input and applies the zoom transform to a group element containing the circles. Data is hardcoded as an array of objects with x, y, radius, and fill color properties. The visualization updates its state with the current transform, allowing for smooth interactive exploration of the circular layout.

zoomable circles with d3 zoom

This example shows a set of colored circles positioned on a light green background, which can be zoomed and panned through mouse or touch gestures. The visualization uses D3's zoom behavior to apply a transform to a group element, updating the state object with each zoom event. The circles are rendered with D3 selections, each assigned fixed coordinates, radii, and fill colors from an inline data array. The code leverages the d3.zoom API and the state management pattern to persist the current transform across re-renders.

Circles with D3 + Zoom

This example demonstrates how to create and interact with circles using D3.js. It renders a collection of colored circles with varied positions, radii, and fill colors on a light green SVG background, set at 70% opacity to show overlaps. The visualization implements zooming through d3.zoom, allowing users to scale the content between 0.5x and 5x magnification by adjusting a transform on a group element. The code uses d3.select and data joins to bind circle data to SVG elements, with attributes set via method chaining.
