Quick and easy
Lucidchart has a clean, intuitive interface that will help you quickly build data flow diagrams. With shapes for external entities, processes, data stores, and more, it's easy to graphically represent the flow of data and model process aspects.
Visio import/export
Do you have co-workers or clients asking for data flows in Visio? Import your Visio files, edit them in Lucidchart, and export them back to Visio. It’s as simple as that! Our app also allows file import for SVG files and other diagramming tools.
Work together
Try inviting others to review your data flows and system flows. If you set specific permissions, they can even edit your work. Since Lucidchart is web-based, all changes will be automatically saved and shared with collaborators.
Share and publish
With easy sharing options, design iterations of your data flow will be fast and pain-free. Publish your data flow diagram as a webpage or download it as a PDF, JPG, or PNG. You can even present your diagram right in Lucidchart.
