摘要
Infographic charts communicate data through cohesive compositions of visual elements such as charts, text, and images. Existing infographic chart datasets primarily annotate individual elements with bounding boxes and category labels. Such element-level annotations do not capture hierarchical and spatial relationships, limiting their use for understanding how elements are organized and related within an infographic and for generating well-organized designs. To address this limitation, we introduce ChartGalaxy++, a richly annotated dataset of 217,195 infographic charts. At the core of this dataset is a scene graph representation, in which nodes represent visual elements and semantic groups, and edges encode their hierarchical and spatial relationships. For real infographics, we construct scene graphs by detecting and progressively grouping visual elements; for synthetic ones, we derive them directly from the generation process. We demonstrate the utility of ChartGalaxy++ through three applications: 1) image-to-scene-graph prediction, 2) scene-graph-augmented infographic question answering, and 3) evaluation of scene graph preservation in image generation. Together, these applications highlight the value of ChartGalaxy++ for advancing chart understanding and generation.
