What is @antv/g-svg?
@antv/g-svg is a package that provides a set of tools for creating and manipulating SVG (Scalable Vector Graphics) elements. It is part of the AntV ecosystem, which is a suite of data visualization tools. This package allows developers to create complex SVG graphics programmatically, making it easier to build custom visualizations and graphical interfaces.
What are @antv/g-svg's main functionalities?
Creating SVG Elements
This feature allows you to create and manipulate basic SVG elements like rectangles, circles, and lines. The code sample demonstrates how to create a rectangle and add it to a group, which is then rendered using the SVGRenderer.
const { SVGRenderer, Group, Rect } = require('@antv/g-svg');
const renderer = new SVGRenderer();
const group = new Group();
const rect = new Rect({
attrs: {
x: 10,
y: 10,
width: 100,
height: 100,
fill: 'red'
}
});
group.add(rect);
renderer.draw(group);
Transformations
This feature allows you to apply transformations to SVG elements, such as translation, rotation, and scaling. The code sample demonstrates how to translate, rotate, and scale a rectangle.
const { Rect } = require('@antv/g-svg');
const rect = new Rect({
attrs: {
x: 10,
y: 10,
width: 100,
height: 100,
fill: 'blue'
}
});
rect.translate(50, 50);
rect.rotate(45);
rect.scale(1.5, 1.5);
Event Handling
This feature allows you to attach event listeners to SVG elements. The code sample demonstrates how to attach a click event listener to a rectangle.
const { Rect } = require('@antv/g-svg');
const rect = new Rect({
attrs: {
x: 10,
y: 10,
width: 100,
height: 100,
fill: 'green'
}
});
rect.on('click', () => {
console.log('Rectangle clicked!');
});
