Fig. 3: One-mode concept networks and organisation networks in Heidelberg.
From: Understanding, communicating, and imagining urban biodiversity in German and Italian cities
The figure depicts one-mode networks for the year with the highest frequency of nodes (left) and one-mode networks for the last 12 months of analysis (right) for Heidelberg. Only the top ten frequent nodes are visualised. The size of the nodes represents the frequency (number of times the concept or organisation appear in the articles in the respective time). The strength of the links is bigger according to the edge weight (number of concepts the actors share with each other or the number of actors that mention the same concepts in the respective time). The organisations are citizens (cyan), economy (yellow), grassroots initiative (green), NGO (red), politician (light blue), public administration (blue), public-sector economy (light green), and science and education (pink) (Supplementary Note 3).
