Simple, elegant spark lines for Angular  Demo

Features

• Simple. Integrate in seconds.
• Scalable. Uses SVG for sharp, scalable graphs. Will fill the parent container, or you can provide a fixed size.
• Beautiful. Built-in gradient support, and customizable smoothing.
• Animatable. Support for on-mount animations where the trend graph draws from left to right.
• Tiny. Zero-dependency, gzips to <3kb.
