Circle Pack Labels

A technique to hack the current d3.layout.pack to add labels by adding a label node into the circle pack data before it is processed. By using the sizes of the children, you add a node to your nested data and create a space using the pack algorithm for the label. You will need to do some filtering to display the labels differently from other nodes at that level, but feel free to use this example as a guide.

I am planning on looking at the d3 code to see how easy it would be to make a build in label layer for this layout. But for now you can follow along with this block if you need circle pack labels today!

Really fun dataset on flight delays that I plan on investigating further: Airline on-time performance data provided by the Department of Transportation's Bureau of Transportation Statistics

This example creates a fixed network graph with dynamic labels using d3.js. The network layout and placement of the nodes and edges was calculated in Gephi and then exported as the graph.json file.

This was inspired from these gists by Mike Bostock: Force-Directed Graph, Multi-Foci Force Layout

Weather Plot - New York 2015

In the example we're looking at historical weather data for New York provided by intellicast.com and wunderground.com. Inspired by weather-radicals.com.

This example uses scales to roll your own radial projection by mapping out the x, y, and r positions. If you are creating a line or an area you can use d3's convenience functions d3.svg.line.radial and d3.svg.area.radial but this is a method you can use if you want to use different graphical elements in a circular layout.

K-Means Centroid Deviation

Added all of the Farmers' Markets data into the kMeans Library by @emilbayes, thank you!

Exploring the idea of using the areas around the centroids to exaggerate that cluster when it deviates from the rest of the clusters. This originates from the question "Which features in each cluster differentiate it from the rest?"

Overlapping Bump Chart

Playing around with the idea of a bump chart comparison with two overlapping areas. Based on Farmers Markets data from data.gov.

Another iteration with step interpolation instead of cardinal.

d3-annotation v2.0

Updated features for d3-annotation, a full post here.

This block uses all three of the new features:

• the nx/ny feature for placing line labels
• default styling, no need to import an annotation css file
• color attribute to color the annotations
• new badge option for the HBO and Netflix nomination callouts
