Same tool, four requests. Every drawing below is a real render.

What you type

Create a top-down Dijkstra shortest-path algorithm flowchart: read a non-negative weighted graph and source s, set the source distance to 0 and all other distances to infinity, then repeatedly select the unvisited vertex with minimum distance, relax its outgoing edges, and mark it visited. Leave vertices whose distance remains infinity marked unreachable, output shortest distances and predecessors, and end.

Then tryAdd a priority-queue update after each relaxed edge.Change the output to show only the path to a target vertex.

The drawing

What a code to flowchart converter makes.

A code flowchart is a visual path through a program. It turns operations into steps, tests into decisions and repeated work into loops, so a reader can follow what happens for each input.

Use it to explain a function, check edge cases or discuss pseudocode before implementation. It models logic as text; it does not execute, compile or run the code you describe.

Flowchart: What a code to flowchart converter makes

Who uses it

Who uses code to flowcharts.

Computer science students

Algorithms and pseudocode made easier to trace before writing or debugging an implementation.

Teachers and technical writers

A concise visual explanation of how requirements become an implemented algorithm.

How it works

How to turn code into a flowchart in three steps.

Describe it

One paragraph is enough to start.

“Create a top-down Dijkstra shortest-path algorithm flowchart: read a non-negative weighted graph and source s, set the source distance to 0 and all other distances to infinity, then repeatedly select the unvisited vertex with minimum distance, relax its outgoing edges, and mark it visited. Leave vertices whose distance remains infinity marked unreachable, output shortest distances and predecessors, and end.”

Every edit keeps a version.

Add a priority-queue update after each relaxed edge.

FAQ

Common questions

What languages can I use for code to flowchart?

Describe logic from Python, Java, C, JavaScript, TypeScript, Go or another language. Focus on the relevant function or execution path, including its conditions and loops.

Does the converter run my code?

No. It interprets the code or description as text and draws the control logic. It does not compile, execute or test the program.

How are loops shown in a code flowchart?

A decision checks the loop condition. One path enters the loop body and returns to that decision, while the other path continues after the loop.

Can I diagram a function instead of a whole program?

Yes. A single function is often the clearest scope. Include its input, key decisions, calls or outputs, then extend the diagram if you need more context.
