A grid of colored shapes on a large SVG canvas demonstrates a hovering effect, with white rectangles and concentric circles in steel blue, blue, dark blue, yellow, and light green arranged across vertical and horizontal green and red lines. The visualization divides the viewport into a parameterized grid using D3 v5's selection API, appending paths and circles via `append`, while styling lines through CSS classes. It uses `d3.zoom` to enable interactive panning and zooming, which updates the group's transform attribute based on the zoom event.

AI-generated description

Goals : - Divide a svg element in 4 sub svg elements

Elements to grasp :

The D3 Select module : understand how DOM elements can be created, selected, modified.

How View port works for french speakers.

This example is used to understand the SVG viewport and viewbox - Ludo;

Improvements since the start : - Style of lines are defined in CSS. - Number of Horizontal and Vertical are parameter - For automatic Display, number of lines and viewbox dimensions are now linked. - Viewbox dimensions is not hardcoded anymore

181202_05_Nested circles

A grid of nested circles and rectangles animates into place on an SVG canvas. The visualization builds a parametric layout of 91 cells, each containing concentric circles with decreasing radii and a grey rectangle that expands during the transition. The code uses D3 v5 selection and range modules to generate and position elements, with the `transition().duration()` API animating the circles from the center outward and rectangles from zero size. Hover effects change fill colors to black.

181202_02_ Put some balls in

This example demonstrates how SVG viewport and viewbox scaling affect the rendering of graphical elements by dividing a single `<svg>` into a grid of paths, circles, and rectangles. The visualization shows a 7-by-30 grid of green and red grid lines, overlaid with blue circles and yellow squares, which can be interactively zoomed and panned using d3.zoom. The code uses D3 v5 selections (`select`, `selectAll`, `data`, `enter`) to generate the SVG elements dynamically, with all styling defined in CSS. The zoom functionality applies a transform to the entire SVG, illustrating how the viewport interacts with coordinate systems.

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.

MB zoom circles in and out

Three circles, colored green, purple, and red, sit on a white canvas as the core subjects of this zooming example. The visualization demonstrates click-to-zoom interactions using d3.zoom, where clicking a circle triggers a smooth transition that scales and translates the view to center on that circle. The code uses d3.v4 with SVG rendering, and the zoom behavior is applied to the entire SVG container while individual circles respond to click events. A background rectangle handles resetting the view when clicked, and the active circle is tracked to toggle between zoomed and reset states. The data consists of a simple JSON array of circle positions, radii, and colors, rendered as SVG circle elements.

Magnifying Effect

This visualization demonstrates a magnifying effect on a grid of lines using a fisheye distortion. The display initially shows a uniform grid of vertical and horizontal paths rendered as SVG. When the mouse moves over the canvas, the code updates the fisheye’s center point and recomputes each path’s coordinates by mapping the original points through the `d3.fisheye` function. The distortion magnifies the area around the cursor, bending the lines outward while preserving the overall structure. The example uses D3 v3 with SVG rendering and custom mouse-event handlers to drive the interactive effect.

181202_02_ Put some balls in

This example shows how to organize SVG elements within a viewport by dividing a single SVG element into four sub-elements using D3 v5’s selection module. It generates a grid of vertical and horizontal paths, along with steel-blue circles, using `d3.range` and data joins. The viewBox dimensions automatically scale with the number of lines, and the code applies a zoom behavior via `d3.zoom` to transform a group element. Styling for the paths is defined in CSS, while circle positions and radii are computed from the grid parameters.

Pan & Zoom III

This example shows a dense phyllotaxis pattern of 2,000 circles that users can pan and zoom with the mouse. The code uses the d3-zoom plugin in D3 v4 to handle input, applying the zoom transform directly to a group element containing the circles. An invisible overlay rect ensures the zoom behavior receives events, while the SVG’s coordinate system is adjusted with a translate transform. The rendering is done via SVG circles, with a resize handler updating the layout.

181202_02_ Divide window_01

This example demonstrates how SVG viewport and viewBox attributes control the scaling and positioning of graphical elements within a designated area. It displays a grid of vertical and horizontal paths, along with a row of circles, all rendered within a single SVG element. The code uses D3 v5 selection methods to bind data and append elements, while CSS styles define the line colors. The viewBox is not hardcoded but is derived from parameterized dimensions for the grid and shapes.
