The paper presents a novel approach to visualize the impacts of design heuristics in sustainable product development. Focusing on the integration of ecological sustainability, our research introduces a multivariate visual approach, combining Sunburst Charts and Radial Heat Maps. The methodology, based on a description standard for design heuristics, enhances knowledge sharing and provides an intuitive tool for designers. A dynamic three-series radial heatmap facilitates comparisons across different product properties, fostering informed decision-making in product development.
