A program that draws concentric circles that expand and end up immitating drifting smoke rings.

Notes:

• This is an attempt to create a basic animation of SVG elements. In this test, data has been substituted for randomly placed circles.
• Inspired by Amelia Wattenberger's great blog post and Nita Nagdewate's concentric circle patterns here in Vizhub.

Success/Failure Notes:

• I originally tried to accomplish this with the Styled-Components plug-in. Although it worked, it proved to be too resource-intensive, especially when so many DOM objects had to be re-rendered.
• I also experimented with the onAnimationIteration and onAnimationEnd global event handlers but couldn't reliably get them to work for this project. Further learning required...
