Path Creation

This feature allows the creation of a new path using the d3-path module. The moveTo and lineTo methods are used to move the cursor to a point and draw a line to another point, respectively.

{"import { path } from 'd3-path';\nconst p = path();\np.moveTo(100, 100);\np.lineTo(200, 200);\nconsole.log(p.toString()); // M100,100L200,200"}

Arc Drawing

This feature enables drawing arcs as part of the path. The arc method takes parameters such as the center coordinates, radius, and start and end angles to define the arc.

{"import { path } from 'd3-path';\nconst p = path();\np.arc(100, 100, 50, 0, Math.PI / 2);\nconsole.log(p.toString()); // M150,100A50,50,0,0,1,100,150"}

Rectangular Paths

This feature is used to create rectangular paths easily. The rect method takes the top-left corner coordinates and the width and height of the rectangle.

{"import { path } from 'd3-path';\nconst p = path();\np.rect(50, 50, 100, 100);\nconsole.log(p.toString()); // M50,50h100v100h-100Z"}

Bezier and Quadratic Curves

This feature allows the drawing of Bezier and quadratic curves. The quadraticCurveTo and bezierCurveTo methods are used to define these curves with control points.

{"import { path } from 'd3-path';\nconst p = path();\np.moveTo(10, 90);\np.quadraticCurveTo(50, 10, 90, 90);\np.bezierCurveTo(130, 10, 170, 10, 210, 90);\nconsole.log(p.toString()); // M10,90Q50,10,90,90C130,10,170,10,210,90"}
