The Growth of a Petition Movement in a Structure of city linked Events
| A visualization of a petition
movement in a German town during the German Revolution of 1848/1849. The
images below show 1200 individuals as small spheres . Each individual is
placed according to his pattern of participation in one or more of
over 60 events (institutional, cultural and local activities). The
events are shown as gray spheres, their size stands for the number of participants.
This very large network has been reconstructed in the research project of Prof.Carola Lipp, Institute of European Ethnology, at the university of Goettingen, Germany, by cross linking a huge database of more than 200 historical documents. The degree of exposure to activists (the number of activists in all
events each single individual participates in) is color coded in the images
below. Exposure is known from the literature to predict, when people become
active themselves

Time 1
Most of the active people (red, orange) are connected to the center of the city. The degree of exposure to activists is modest compared to the later time periods. Almost all individuals in the periphery have very few contacts with activists |
|
 |
Time 2
Exposure in the center has grown and spread. Many clusters in the semi periphery are now exposed at moderate (light blue) to medium levels (green and yellow). In the periphery on the left, we find a separate green cluster of activists which is only weak connected to the center |
|
 |
Time 3
While the peripheral group from time 2 has ceased to be active the exposure to activists has grown to even higher levels in the center, as is true for many of the clusters in the semi- periphery |

| All three images together as an animated gif help to give a deeper
understanding how the movement diffuses in the structure :
