    1. COThe reason the world map you found says it's not recommended for choropleths is because it's a mercator projection. The problem with this projection is that it distorts the areas; northernmost and southernmost regions appear disproportionately larger than regions near the middle. The page you found essentially claims that coloring each country based on some metric is a bit like comparing apples and oranges, because your audience might be mislead by the disproportionate sizes of regions and make some wrong assumptions about the data being represented by the colors.

    2. COThat's not to say that there are any technical issues preventing you from being able to use that world map to create a choropleth map, but you have to be careful about the claims you're making with it. I don't know about any projections that maintain proportionality for the entire world without introducing other kinds of distortions. There are all kinds equal-area of projections described [on this page](http://en.wikipedia.org/wiki/Map_projection#Equal-area), but they introduce other kinds of distortions. And... producing an SVG of one of those projections is probably not going to be easy.

    3. CO@meetamit thanks. Yeah, I understand that. So even if I wanted to use that map, or another, where do I get the world equivalent of "../data/us-states.json"? Do I have to generate that myself? I guess I thought D3 had that kind of thing available as a plug-in or something. Seems like http://jvectormap.com/ is the easier way to go for my purpose.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
