You can use the data import feature to upload your data and auto-generate a diagram. Select your spreadsheet file type and verify the data set to be imported. If your data is linked to Google Sheets, Excel, or CSV, easily refresh and update your diagrams as you make changes to the data or simply upload a new CSV. If you've already created a diagram, you can also import it from Visio®, Gliffy, or OmniGraffle and pick up right where you left off.

The best way to create a huge master diagram would be to link a few different diagrams together using Hotspots. Hotspots are essentially shapes in Lucidchart that link to other webpages. You could create your larger master diagram, then create Hotspots that link to separate smaller Lucidchart diagrams for marketing or other functions. So, when you follow the flow in the larger diagram and reach the end of one branch, you will reach a Hotspot link that will take you into a separate diagram.
