What SVG stands for?
SVG stands for Scalable Vector Graphics.
What is SVG?
SVG is a XML based format to draw vector images. It is used to draw two − dimensional vector images.
What are the features of SVG?
Following are the core features of SVG −
·         SVG, Scalable Vector Graphics is an XML based language to define vector based graphics.
·         SVG is intended to display images over the web.
·         Being vector images, SVG image never loses quality no matter how they are zoomed out or resized.
·         SVG images supports interactivity and animation.
·         SVG is a W3C standard.
·         Others image formats like raster images can also be clubbed with SVG images.

What are SVG filters?
SVG uses <filter> element to define filters. <filter> element uses an id attribute to uniquely identify it.Filters are defined within <def> elements and then are referenced by graphics elements by their ids.

Linear Gradients represents linear transition of one color to another from one direction to another. It is defined using <linearGradient> element.
What is Radial Gradients in SVG?
Radial Gradients represents circular transition of one color to another from one direction to another. It is defined using <radialGradient> element.
