Modes

Vim has two modes insertion mode and command mode. The editor begins in command mode, where the cursor movement and text deletion and pasting occur. Insertion mode begins upon entering an insertion or change command. [ESC] returns the editor to command mode (where you can quit, for example by typing :q!). Most commands execute as soon as you type them except for "colon" commands which execute when you press the ruturn key.

Quitting

• :x Exit, saving changes
  
• :q Exit as long as there have been no changes
  
• ZZ Exit and save changes if any have been made
  
• :q! Exit and ignore any changes

I stumbled across this workflow while doing a piece I shared in /r/dataisbeautiful. Other people may have come across it as well, but I thought I'd post it here just in case it's new to some. It's useful when you're doing a piece that has multiple, custom visualizations per page, and the existing D3-charting libraries aren't working for you.
Basically it works like this:
Data Loading
Host your data in Google Spreadsheets since that makes it easier to manage and update it. Use a separate sheet for each data set.
Use Tabletop to extract the data. You can use its callbacks to load separate sheets parallel to improve load time (example here).
Data Transformation
Since the data is often put in a similar form for each chart, I created a special mini-library for transforming the data. I used Underscore.js (of course) to get the data in a good form for D3.js.
The code above might look a little weird since I'm doing some magic to get each data element to refer back to its parent object. That's to support a Voronoi lay
