However, as qualitative and static representations, CLDs are limited in their ability to support dynamic analysis and inform intervention strategies. We propose Diagrams-to-Dynamics (D2D), a method for converting CLDs into exploratory system dynamics models in the absence of empirical data. With minimal user input—following a protocol to label variables as stocks, flows or auxiliaries, and constants—D2D utilizes the structural information already encoded in CLDs, namely the existence and polarity of causal connections, to simulate hypothetical interventions and explore potentially influential places to intervene, known as‘leverage points,’under uncertainty.  \nResults: D2D helps distinguish between high-and low-ranked leverage points. We compare D2D to a calibrated system dynamics model constructed from the same CLD and variable labels. D2D showed greater consistency with the calibrated model than did static network centrality analysis, while also providing uncertainty estimates and guidance for future data collection.  \nConclusions: The D2D method is implemented in an open-source Python package and a webbased application to support further testing and to lower the barrier to dynamic modeling for researchers working with CLDs. Future studies could help establish the approach’s utility across a broad range of cases and domains.  \nKeywords: causal loop diagram, system dynamics, analysis, network, quantification, package, Python  \nBackground  \nComplex problems arise from interacting components that form feedback loops operating across multiple scales [1, 2] . Addressing them requires moving beyond reductionist approaches and capturing the dynamic interplay between biological, psychological, and social factors [3–5] . Accordingly, complexity science has gained traction in fields like public health [3–7], psychology [8–12], and environmental sciences [13–15], offering novel ways to analyze these interconnected systems.  \nAs a key tool in complexity science, causal loop diagrams (CLDs) are increasingly used to explore and communicate the feedback mechanisms underlying complex problems. In health sciences, areas of application have included chronic stress [16, 17], workplace well-being [18], depression [19, 20], and concussion [21] . CLDs map causal connections between key system variables to gain insight into such problems and identify ‘leverage points,’ i.e., intervention targets hypothesized to significantly influence system behavior [22] . The analysis of leverage points often relies on visual inspection [23] or structured qualitative approaches like Meadows’12 Places to Intervene in a System [22], the Intervention Level Framework [24], orthe Action Scales Model [25] .
