NOTA BENE: Because Blocks use iFrames, you'll have to open this visualization in its own tab/ window to see the chart resize with the window resize.
For sake of reference, toggle the radio buttons to get .tvs with variable rows of data. Up to several hundred data points will resize with ease, but at over 1000, the browser starts to hurt on window resize.
The line chart itself is, of course, based on Bostock's original example here.
