The network map displays multiple clusters of nodes, each represented by circles with labels, connected by thin lines indicating relationships, with labels adjacent to the nodes. At the center, a large blue node labeled “artificial intelligence”, is directly connected to the nodes “technology adoption”, “a i”, “machine learning”, and “smart cities”. Above this cluster, a red node labeled “machine learning”, is connected to “a i adoption”, “smart city”, and “sustainability”. To the lower right, a green node labeled “smart cities”, is connected to the nodes “digital twins”, and “predictive analytics”.Keyword co-occurrence
