Density Mapping in Google Maps

Google API add-on lets you make heat maps inside a Google Map portal!

HeatMapAPI can be used over the Internet or as a .NET DLL that runs in a local environment and allows you to integrate heat map images into Google Maps or other GIS systems.  In this post we’re going to use HeatMapAPI to visualize the density of recent Starbucks store closures.  In a recent statement, Starbucks announced the closure of 600+ stores in the United States due to economic conditions.

In other news, we’d like to thank Starbucks for providing their easily-parsed list of closures. Most visualizations I’ve seen are using this dataset.

German Immigrants in the USA

A map of the USA showing where bars outnumber grocery stores.

Bars outnumber grocery stores

FloatingSheep, a fun geography blog, looks at the beer belly of America. One maps shows total number of bars, but the interesting map is the one above. Red dots represent locations where there are more bars than grocery stores, based on results from the Google Maps API. The Midwest takes their drinking seriously.

Introducing News Dots – By Chris Wilson – Slate Magazine

From Slate: News Dots. This little Flash-driven app renders the day’s events as a social network.

Like Kevin Bacon’s co-stars, topics in the news are all connected by degrees of separation. To examine how every story fits together, News Dots visualizes the most recent topics in the news as a giant social network. Subjects—represented by the circles below—are connected to one another if they appear together in at least two stories, and the size of the dot is proportional to the total number of times the subject is mentioned.

Graceful Timelines

We’ve all seen the unreadable timelines created by some analysis software. The hard lines, the veering connections. The mis-sized and aliased fonts. These might be sufficient for experts, but in the fullness of time, other more polished options will arise. Now you can make those veering connections into swooping connections.

The cartoon site XKCD.com did a few timelines for very complicated movie plots (Lord of the Rings, Star Wars trilogy, etc), modeling them after the famous “Napoleon’s Russian Campaign” chart. Sample:

Napoleon in Middle Earth

Anybody who has tried to write a mega-selling spy novel knows that the hardest part about plotting is getting all the interactions and conflicts on one page. Now we have a super online tool to help us do just that.

Introducing cs448b Data Visualizationhttps://graphics.stanford.edu/wikis/cs448b-09-fall/FP-OgievetskyVadim.

See the project description. Here is a sample poster.

The interface for the online tool (which is available here):

Plotting out the latest Mossad exploit? Wanting to show hookups in a crime family? This might be the tool for you. Project creator Vadim Ogievetsky says,

My main goal is to implement an efficient and effective layout algorithm that, with the users help, would generate results similar to the hand crafted images shown above. The layout algorithm will use combinations of genetic algorithms and simulated annealing to achieve the goal.

IDV Solutions Collision Watch

Absolutely beautiful: Zooming, interactive heatmap presenting all the traffic fatalities of 2007 in the United States where alcohol was involved.

This is a demo app for Visual Fusion software, which looks very interesting itself.

ClearMaps: Actionscript Data Visualization

From Sunlight Labs:

Despite the recent explosion of web based cartography tools, making effective maps for data visualization remains a challenge. While tools like Google Maps are great for helping navigate the world they are often poorly suited for thematic mapping, as many features like roads and cities only get in the way of telling compelling stories with data. In fact, even the distance between places can be a distraction – who cares how far away Alaska is when the goal is to make a simple comparison between US states?

Here’s the github project so you can play around:

OpenStreetMap and Haiti Relief

Here is a visualization of the efforts of an impromptu crowd community to produce accurate maps of Haiti following the earthquake. Each dot shows a volunteer contribution–and the blue dots show camps of displaced people. An astonishing amount of information, but then, many hands make light work.
