The world’s top 50 billionaires: A demographic breakdown.

The world’s top 50 billionaires: A demographic breakdown.

With Slate’s Top 50 Billionaire Breakdown, we attempt to visualize the richest of the rich by paring them into demographic categories: age, location, industry, source of wealth, education, and religious affiliation. Some of the sortings are heartening: There are more self-made men than born-rich kids in the top 50, and the self-made billionaires’ total wealth is bigger. Vis. Stephen Boak — Easy as (a) Pie. Through my work at Boundary I’ve started playing with the D3 visualization library, trying to build some interesting visualizations for our real-time network monitoring dashboard.

Stephen Boak — Easy as (a) Pie

I’ve really been enjoying D3 and Mike Bostock, the creator, has been extremely helpful to me and lots of others in the d3-js Google Group. Since the library is new, I hope the series of experiments I post here can be helpful in spreading some knowledge and awareness of the library. What You’re Building My first experiment is an animated pie chart meant to visualize a breakdown of incoming network traffic by port. DataMaps. Let’s Make a Map. In this tutorial, I’ll cover how to make a modest map from scratch using D3 and TopoJSON.

Let’s Make a Map

I’ll show you a few places where you can find free geographic data online, and how to convert it into a format that is both efficient and convenient for display. I won’t cover thematic mapping, but the map we’ll make includes labels for populated places and you can extend this technique to geographic visualizations such as graduated symbol maps and choropleths. Without further ado, here’s the map: Shown are the four constituent countries of the United Kingdom: Scotland, Northern Ireland, Wales and England. As maps go, it’s not particularly interesting, but the simplicity should serve adequately to demonstrate the basics of map-making. From Shapefile to GeoJSON - Jim Vallandingham. A method for editing, merging, simplifying, and converting Shapefiles to GeoJSON D3.js supports cartographic visualizations by being able to display lines, polygons, and other geometry objects .

It uses GeoJSON as the storage format for this type of visualization. Likewise, map tiling libraries like Leaflet can use GeoJSON to create map layers . Mapping with D3. Trying out D3's geographic features. Hover over a county: There's nothing special about this map. How to Make Choropleth Maps in D3. Even if you think you don’t know what a choropleth map is, chances are you’ve seen one. And come November 2012, you’ll see plenty: one iconic example of a choropleth map is a map of the United States, laid out in red and blue, showing the results of a presidential election. Choropleth maps can be simple, like in the example above, where the color of the state indicates whether the state goes in one direction (Democrat) or the other (Republican). The states can also be colored on a scale to indicate data, with a color like blue representing a low number and red representing a high number, leaving a number in between to be purple. These simple visualizations make large amounts of data easy to understand at a glance, allowing insights that would take much longer if you’re looking at a table of numbers.
