Line
A line is a graphical element or mark defined by endpoints that represents a straight segment or connects plotted data positions.
D3.js in Action, Third Edition
An SVG line is a line element defined by two endpoint coordinates and rendered as a straight segment.
- How it is used
- Uses straight SVG segments as fundamental shapes in D3 visualizations.
- How deep it goes
- Explains endpoint coordinates, stroke styling, and container clipping without deeper SVG rendering internals.
- Examples
- Builds a gallery line from (50,45) to (140,225), then styles it black with width 3.
- What you can do after
- Build it from scratch with endpoint coordinates and visible stroke attributes inside an SVG container.
Data Storytelling with Altair and AI
A line is a graphical mark that connects plotted data positions to represent continuity or progression.
- How it is used
- Connects sequential campaign options to turn a set of rectangles into a visualized roadmap.
- How deep it goes
- Defines endpoint coordinates and demonstrates Altair rendering, stopping short of general line-chart analysis.
- Examples
- Uses connectors between Online Campaign, Influencers Engagement, and Social Media Promotion rectangles.
- What you can do after
- Builds an Altair roadmap by specifying line endpoints and combining the line with rectangles and labels.
