  Words & Votes: The Changing Congressional Opinions on Gun Violence

  Posted: 17-May-2013, 11:34am EDT

  
  The political visualization Words & Votes [sandyhookpromise.org], developed by digital agency R/GA for non-profit organization Sandy Hook Promise, provides a comprehensive look into the opinions of congressional representatives on the issue of gun violence.

  More specifically, the visualization tracks each member of congress as being "neutral", on the side of "Gun Safety," or on the side of "Gun Rights". It then maps the evolution of these opinions over time on a vertical timeline.

  These individual opinions have been based on two separate types of information: the analysis of the tweets sent by members of Congress and their voting record on Capitol Hill on laws and bills that relate to gun violence.

  Individual members of congress can be explored in terms of being influential or vocal, or filtered by address, zip code or home town.

  How Half a Second of High Frequency Stock Trading Looks Like

  Posted: 13-May-2013, 4:57pm EDT

  
  The movie shown below, developed by a real-time trading software developer Nanex, shows the stock trading activity in Johnson & Johnson (JNJ) as it occurred during a particular half a second on May 2, 2013.

  Each colored box represents one unique exchange. The whote box at the bottom of the screens shows the National Best Bid/Offer, which often drastically changes in a fraction of a second. The moving shapes represent quote changes which are the result of a change to the top of the book at each exchange. The time at the bottom of the screen is Eastern Time HH:MM:SS:mmm, which is slowed down to be able to better observe what goes on at the millisecond level (1/1000th of a second).

  In the movie, one can observe how High Frequency Traders (HFT) jam thousands of quotes at the millisecond level, and how every exchange must process every quote from the others for proper trade through price protection. This complex web of technology must run flawlessly every millisecond of the trading day, or arbitrage (HFT profit) opportunities will appear. However, it is easy for HFTs to cause delays in one or more of the connections between each exchange. Yet if any of the connections are not running perfectly, High Frequency Traders tend to profit from the price discrepancies that result.

  YouTube Trends Map: Explore the Most Popular Videos by Location

  Posted: 9-May-2013, 3:10pm EDT

  
  The YouTube Trends Map [youtube.com] is a visualization of the most shared and viewed videos in various regions across the United States over the last 12 to 24 hours. It accompanies the more analytical Trends Dashboard to provide a full overview of the the rising videos and trends on YouTube in terms of actual views or shares, filtered by geographical location, gender or age of the viewers.

  The demographic information of viewers is solely based on the information reported by registered, logged-in users in their YouTube account profiles. Next to the geographical map, the Trends Map also include a series of horizontal bar graphs, each representing a graphical summary of the top videos for a different demographic. Within each bar, a video is represented by a colorful segment, the colors are drawn from the video's thumbnail. The width of a video's segment reflects the number of regions on the map where the video is #1.

  Mapping the Pavement Quality of Streets in L.A.

  Posted: 9-May-2013, 4:15pm EDT

  
  L.A. Street QualGrades [latimes.com], developed by the Los Angeles Times Data Desk, maps the pavement quality rating for each of the 68,000 street segments in L.A., the largest municipal system in the US with about 6,500 miles of paved roadway streets.

  Using a state-of-the-art van equipped with cameras and lasers, the Bureau of Street Services graded each single street segment of L.A.'s vast street network from from A (dark green) to F (dark pink). The grades were based on a 100-point scale called the "pavement condition index".

  Bolides: Explore the Eye-Witnessed Meteorites that Collided with Earth

  Posted: 3-May-2013, 5:20pm EDT

  
  Bolides - Visualizing Meteorites [bolid.es] by data visualization designer Carlo Zapponi visualizes all historical occurrences of meteorites that collided with the Earth and were eye-witnessed when falling and hitting the ground.

  The visualizes is comprised of a linear timeline of which the top denotes the number of meteorites spottings per year, and the bottom shows their mass, estimated in kilograms. The dataset includes 34,513 recordings of found and fell meteorites that have not been classified as doubtful or discredited. A meteorite is classified as 'fell' if it has been observed by people or automated devices during its fall.

  Chesapeake Bay Grasses: Tracking Underwater Vegetation over Time

  Posted: 26-April-2013, 6:31am EDT

  
  Chesapeake Bay Grasses [chesapeakebay.net], designed by Stamen Design is an interactive map that tracks a quite exotic subject: the changes of the underwater grasses at Chesapeake Bay, the largest estuary in the United States.

  Accordingly, the map reveals how the fluctuations in water temperature, salinity and turbidity correlate to grass abundance, as dominant species ebb and flow and grass beds shrink and expand over a period of 30 years.

  TweetMap ALPHA: Querying a Massive Amount of Tweets on a Map

  Posted: 23-April-2013, 3:58pm EDT

  
  The impressive TweetMap ALPHA [harvard.edu], developed by Harvard University's Center for Geographic Analysis, is based on a dataset of about 95 million tweets, which can be dynamically queried by time, by location or by keyword.

  Tweetmap makes use of so-called special Graphic Processing Units (GPUs) to parallelize the hard-to-compute job such as the querying and rendering of the very large dataset on-the-fly. As such, the online map shows individual tweets as unique dots, but also aggregates them as a heatmap. In addition, the a series of maps can be generated and explored by time, ranging from days to mere seconds.
