Two identically sized SVG viewports render grids of vertical and horizontal lines using D3’s data join with `selectAll`, `data`, and `enter`. Each grid’s line count is set by parameters, and the viewBox dimensions are derived from those counts rather than hardcoded. The example demonstrates how varying the SVG `width` and `height` attributes changes the display of the same coordinate system, while CSS classes style the lines separately from the geometry.

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_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.

181202_01_Viewport

This example demonstrates how the SVG viewport and viewBox interact to scale a coordinate system. A set of vertical and horizontal path elements, drawn as colored lines, is defined within a viewBox of “0 0 100 50” and rendered inside an SVG element with a blue border. The number of horizontal and vertical lines is parameterized, and their positions are calculated dynamically using D3’s `range` function. The code uses D3 v5 to append paths to the SVG, while line styling is specified in an external CSS file.

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.

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.

181202_04_ Nice hoevering effect

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.

Responding to Resize

This example demonstrates a simple SVG visualization that dynamically resizes to fill the browser window. It uses CSS to define a full-viewport container and JavaScript to read the container’s client dimensions on every window resize event. The code appends an SVG and redraws two crossing lines to form an X, updating the SVG’s width and height attributes. It relies on D3 v5’s selection and data-join methods (`selectAll`, `enter`, `merge`) to manage the line elements, with no external data source.

HTML Starter

This example renders a lightweight grid visualization inside an SVG element, with horizontal and vertical lines spaced every 20 pixels across a 960-by-500 canvas. The static grid serves as a simple geometric backdrop, demonstrating basic SVG construction without any interactive or data-driven elements. The code uses the d3.select and d3.append APIs to build the grid lines, applying a gray stroke via CSS classes. The dataset is generated programmatically from the SVG’s dimensions, and the rendering relies solely on vector shapes defined in pure SVG, with no external data source or animations involved.
