A method and system for visualization interaction design for cross-platform utilisation is described. The system includes a unified user interface interaction module and a visualization module. The visualization module generates an interactive graph for data visualization. The unified user interface interaction module includes a unified user interface module configured to receive an operation on the interactive graph. The unified user interface module includes a pointer user interface module and a touchscreen user interlace module. The visualization module updates the interactive chart from the operation on the interactive graph with the corresponding user interlace module.
