Please add a way to resize the text on the arrow connections.

[Tylersuard]

Proposal

For example: in the following chart, I am able to resize the text inside the modules, but I can't resize the text on the arrows connecting them.

flowchart LR
classDef largeText font-size:20px;
A["User"] -- Question --> B["Chatbot"]
B -- Chatbot Answer --> C["LLM"]
A -- Answer --> C
C --> D{"Chatbot Answer"}
D -- Yes --> E["Result: Pass"]
D -- No --> F["Result: Fail"]
class A,B,C,D,E,F largeText

Example

flowchart LR
A["Evaluation Box"] -- Eval Question{fontsize:18} --> B["Chatbot"]

You can use linkstyle statement to handle this. See example below:

linkStyle 0 stroke:#ff3,font-size:18px;

Since there is no "id" associated with the link itself we are using the index position to apply the style. So while you cannot do the same classDef styling as you can with nodes, you can style each link separately.

The only drawback to this syntax is that if you move your links around, the indexes will be off and you will have to renumber
