Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.

D3: Async Arc Progress Gauge / Meter

View on bl.ocks.org/cmdoptesc/e9b3bfc6f43b4bd237e2

Forked from Bostock's original Progress Events example to answer Rex X's post on the d3-js group:

The progress meter is based on the number of files that have downloaded. In our case, numberOfFiles is set to 20.

We then generate 20 random durations between 0 - 3000ms to simulate download times, and call setTimeout using the durations. Each timer then calls update, which increments the number of files downloaded, increasing the progress arc with a tweening function.
