In this visualization mode, activated when both concentration (conc) and energy (energy) metrics are specified for all network entities at a chosen time step, rNets illustrate the reaction dynamics. Node backgrounds depict compound concentrations, using a color gradient normalized for immediate clarity, and arrow widths signify reaction rates-wider arrows indicate faster reactions. Directionality is inherently shown by the net reaction rate, without the need for explicit direction markers. This design, with concentration and rate normalization, offers a direct, unified view of the reaction network's kinetics and dynamics at any simulated time step. Normalization of concentration and rate values ensures consistent visualization scales. For detailed computational methods behind these values, see Note S2.
