An SVG element belongs to an SVG document and defines or contains vector graphic content. D3 commonly uses an SVG container to hold shapes that form a visualization. section 2.0 section 1.2.1
Create an SVG element by selecting a container and chaining append(). The new node enters the DOM even when it produces no immediately visible change. section 2.4
Add an SVG container with D3
d3.select(".responsive-svg-container") .append("svg"); This inserts an SVG element inside the selected div. Later, SVG shapes can be appended inside it and configured with attributes and styles. section 2.4 section 2.0
Use SVG elements effectively by remembering these DOM rules:
- Set position, size, and proportions through SVG attributes. section 1.2.1
- Append shapes inside an SVG container to construct a visualization. section 2.0
- Control drawing order through DOM order: later SVG elements appear on top of earlier ones. section 1.2.1
d3.select(".responsive-svg-container")
.append("svg");
