Interactive Diagram Maker
Turn any shape into a clickable trigger that reveals details on demand. Share with a link, no login required for viewers.
What is an interactive diagram?
An interactive diagram is a diagram whose shapes, regions, or layers respond to viewer input such as clicks, taps, or hovers. Instead of showing every detail at once, an interactive diagram presents an overview and lets the viewer reveal additional information on demand. The result is a single artifact that serves both quick high-level scanning and deep exploration.
Common types of interactive diagrams include:
- Clickable diagrams. Individual shapes act as triggers that open popups, tooltips, or any other text or diagram content with more detail about that element.
- Drill-down diagrams. Clicking a shape opens a nested sub-diagram or detail view, letting viewers navigate from a high-level overview down to specifics, diving "into" shapes and text.
- Layer-toggle diagrams. Viewers turn groups of shapes on and off to compare states, isolate subsystems, or step through a process.
- Inter-linked diagrams. Shapes carry hyperlinks that navigate the viewer to external documents, pages, or other diagrams.

The problem with static diagrams
Most diagrams need more detail than fits on the diagram itself, so the detail ends up in a separate document. It becomes a bit of a pain to make changes, as now there are two different resources that need to stay in sync.
Linking to a slide deck, or exporting to a PDF, doesn't help much; since these are still static formats, when someone needs context on a particular step, they'll have to come back and ask you about it.
Some tools try to address this. Visio lets you hyperlink shapes to an Excel sheet or other Visio docs, but that means maintaining three files, and requires Visio on the viewer's end. Draw.io and Lucidchart support layer toggling, but actually adding interactivity to your diagram feels more like an afterthought rather than the main point.
The missing piece is a clickable, shareable diagram where anyone can drill down into the details behind any individual shape.
How to create an interactive diagram
-
Draw your diagram. Use Vexlio's diagramming tools to create block diagrams, system architecture, network topologies, process maps, org charts, or any other kind of diagram.
-
Add popup content to any shape. Select a shape and click "Add Popup." This opens a popup canvas where you can add whatever detail belongs to that shape: text, images, links, checklists, code snippets, or even a nested sub-diagram. The result is a diagram with popup details behind every shape that needs them.
-
Choose how popups appear. Configure each popup to open on click or on hover, per shape. Click-to-open works well when you want viewers to actively explore, while hover is better for lightweight tooltips that reveal context at a glance.
-
Publish and share. Generate a single shareable link. Anyone with the link can view and interact with the full diagram, clicking shapes to reveal their popup content. Viewers don't need a Vexlio account or any software beyond a browser.
Each popup is a full Vexlio canvas with no restrictions on size, content types, or appearance. You can put as much or as little detail as you want behind each shape.
Why make your diagrams clickable?
Static diagrams tend to push you toward one of two extremes: pack in every detail and make the diagram hard to read, or leave detail out and attach a separate explainer doc. Clickable diagrams offer a middle path, where the overview stays clean and specifics are available on demand behind each shape.
This matters most when you're sharing diagrams with people who didn't build them, whether that's stakeholders reviewing a system architecture, new team members onboarding onto a codebase, clients exploring a process on their own, or auditors checking compliance documentation.
In each of those situations, the viewer benefits from understanding the big picture first and drilling into detail only where they need it.
Use cases for interactive diagrams
QC sampling — SOP
CFR 21 Part 211Process documentation and SOPs
Picture a pharmaceutical R&D team running a new drug development program that spans years of preclinical and clinical work before NDA submission. The top-level timeline shows the major milestones; click any one and a popup surfaces the governing SOP, names the PI accountable, and links into the trial master file, with the relevant FDA guidance cited inline. A stakeholder can walk the entire program from one URL instead of cross-referencing a PDF, a SharePoint folder, and an Excel sheet. When study details change, the team updates one popup rather than reconciling three documents. Vexlio is used in regulated industries for exactly this: share a single link to an interactive process map instead of emailing static exports.
Interactive decision trees
Consider a customer-support team handling a refund-request triage tree. The branch points are subscription type, account age, reason code, and amount tier. Each branch point opens a popup with the relevant policy text, written out in language the rep can relay verbatim, plus a screenshot of the back-office tool and an escalation path for the trickier calls. The same tool applies anywhere a yes/no path needs to carry the reasoning, citations, or procedure behind each branch.

System architecture and engineering diagrams
Semiconductor manufacturers can publish product block diagrams where each functional block, such as a PMIC, a DSP, or a serial interface, opens onto its datasheet section with the pinout, reference designs, and other details reachable from that one click. Customers drill down from the high-level architecture into datasheet-level depth in the same view, and the manufacturer maintains a single diagram rather than keeping multiple documents in sync manually. Or, consider SaaS architecture pages where each microservice opens to API docs and a runbook link, or network topology maps where each switch popup carries config and the on-call contact. Vexlio lets you build it yourself.
Onboarding and training
For new engineers' first-week orientation, an interactive diagram lays out steps like "set up the dev environment," "request access to staging," "join the on-call rotation," and "ship your first PR." Click any step and the popup pulls up its checklist, showing screenshots of the right internal tool, relevant hostnames, or the Slack channel to ping when the new hire is stuck. New hires move through it at their own pace, clicking into detail when they need it.
Stakeholder communication
Consider a quarterly board update on a multi-year migration. The diagram shows the program at a glance: workstreams up top, milestones threaded through with dependencies, and color-coded status on each one. Executives stay at the overview, while the program manager clicks each milestone to surface the underlying context along with whoever owns the milestone, when it's due, and any active blockers. Procurement clicks the vendor box for contract status; legal clicks the data-residency box for jurisdictional notes. Everyone explores at their own depth from one shareable link.
How other tools approach interactive diagrams
Most diagramming tools weren't built with per-shape interactivity in mind, so they bolt it on in different ways.
Lucidchart and draw.io use layer toggling to show or hide groups of shapes. This works for simple cases where you want to reveal an entire layer at once, though it's not quite the same as clicking a specific node to see that node's detail. Draw.io also supports basic tooltips and hyperlinks on shapes, but rich per-node content requires workarounds with custom JSON links.
Visio supports hyperlinks on shapes that link out to external documents. The detail lives outside the diagram in separate files, and viewers need Visio or a Visio viewer installed to interact with it.
Vexlio builds interactivity into the diagram itself. Any shape can carry popup content: text, images, sub-diagrams, code snippets, links. The published result is a self-contained interactive document that viewers open in any browser with no login and no install. You edit the diagram and its popups in one place, so they can't drift out of sync.
