3D thematic map showing the semantic convergence of 54 key terms in biofuel research across Chile, Colombia, Mexico, and Peru. Term coordinates were derived from co-occurrence data, while elevation (Z) represented the total link strength. Colors indicate thematic clusters identified through the Louvain algorithm, revealing shared research fronts in waste management, thermal processes, and biomass valorization.
