Getting to Know SVG
Explore how SVG works as a scalable, math-based image format essential for creating crisp, flexible graphics with D3.js. Understand the benefits and limitations of SVGs and why they're ideal for interactive web visualizations. This lesson prepares you to leverage SVG’s power without needing to memorize every detail, as D3 handles complexity behind the scenes.
We'll cover the following...
D3 is commonly used with something called Scalable Vector Graphics (SVG) to create graphs and charts. SVGs have been around for a long time, and they are quite powerful.
SVG is a text-based image format. Whenever we think of images, we tend to think of a group of pixels on the screen combined to make up something we can visually recognize.
