 This interface concept of an interactive flowchart proposes the combination of linear audio narration with non-linear open-ended exploration, offering a novel way to understand and navigate complex issues. The interactive flowchart is designed to be inviting and engaging, allowing viewers, readers, and learners to follow a guided tour through a flowchart and pursue their own paths through its contents.
