1. This is a visualization of US expansion in North America from 1700 to 1900, seen through changes in the spatial distribution of post offices.

    Data from the USPS Postmaster Finder, with lat/long coordinates extracted from placenames through correlation with the USGS Geographic Names Information System.

  2. This is mainly an experimentation with soft bodies using toxi's verlet springs.
    The data refers to the evolution of the top 4 maritime empires of the XIX and XX centuries by extent. The visual emphasis is on their decline.

    UPDATE – some minor fixes: no flickering and more robust simulation.

  3. The decline of the largest maritime empires of the 19 and 20th centuries.
    A more sober and formal approach. The physics engine was tweaked in order to attain fluid interactions and a mitosis like split. Added the original 13 colonies (USA). Added Ireland. Cuba maintains its perceived independence date for the consistency of the chosen dates for the other territories.

    There is more information displayed, as the former colonies persist on the map and head to their current geographical positions. Therefore it is possible to visualize in the end of the narrative how much of the world was once part of an Empire. The timeline is no longer linear as it speeds up if there is nothing going on.

    The music was kindly composed for the purpose of this narrative by CHOP WOOD – chopwood.eu

    The Morphing City is a visualization study where a city mutates its shape accordingly with the traffic on its main arteries. Those morphs tend to translate the actual perceived distances within a city, bypassing the common perception based on its geographical mapping.

    This visualization model was executed for the city of Lisbon. To attain it, topological information was gathered from OpenStreetMap to build a skeleton for the city based on its main arteries. The bones of the skeleton are springs that get compressed or distended accordingly with the detected velocities over it. Those distortions affect all the neighboring points and springs as the system is all interconnected.

    The data concerning the velocities was gathered in the context of the CityMotion project, and it pays respect to 1534 vehicles in the city of Lisbon during October 2009. That data was averaged to a single day, and aggregated by periods of one hour. Those periods overlap in 50min, meaning that they are iterated by ticks of 10min.

    What is being displayed are the distortions on each artery that affect the entire city. If the current speed on that artery is below its average global speed, the artery is compressed (the higher the velocity, the smaller the perceived distance). Similarly, if the speed is over the computed (during pre processing) global average, the artery is distended. The colors also reflect those distortions, with positive deviations translating warm colors, and negative deviations translating cold colors.

    Another way to perceive the morphs in the city during the day it's the deformed grid on the bottom right corner of the artifact.

    It's interesting to notice how the city stays compressed during the evening, and how it abruptly expands during the rush hours: 8h-9h and 18h-19h. It's also interesting to see that the 8h-9h period is by far the most problematic.
