Microsoft Visio for Office 365 is the simple online flowchart maker. Visio Online comes with modern UI and an intuitive Getting Started experience. If you don't know where to start, pick from templates for a variety of audiences, including basic flowcharts, process diagrams, timelines, business matrixes, SDL diagrams, and more. Visualizing information is easy—just drag and drop shapes onto the canvas, change a shape’s color or the overall diagram theme, and quickly link one shape to another with connectors.
