D3: Rect Transition: Size, Color, Location

Forked script below was adapted from v3 to v4

D3.js Rect Transition

• Requires d3.v4.min.js library.
• .attrs({}) is a v4 setter containing multiple attribute tuples and requiring d3-selection-multi.v1.min.js plugin, e.g. .attrs({width: 500, height: 200}). Replacing v3’s .attr({}).

Forked v4 script above. Original v3 script below.

D3.js 3.5.17 has an existence similar to Python 2.7.13. Maintained to avoid alienating v3 users.
