# triangle as hand-written SVG (no diagram engine)

Human-Knowledge at the apex, `za` and `AI` as the two base vertices,
three edges closing the triangle. Boxes are drawn after the lines so they
mask the line stubs — no arrow-routing needed for something this small.

# rank

Getting user and ai on top, old and km side-by-side below. Rank comes from edge direction, and old ---> user currently forces old above user. Use TB with subgraphs to pin the rows:

```mermaid
---
title: wow, 4 obj
---
flowchart TB
  subgraph r1 [ ]
    direction LR
    user((User))
    ai((AI))
  end
  subgraph r2 [ ]
    direction LR
    old[["Coding, Syntaxes, Debugging, Languages, DB, Networks, OS, Protocols ..."]]
    km{"`Management of **Knowledge**`"}
  end
  user <-.-> ai
  user --o km
  ai <---> km
  old --> user
  style r1 fill:none,stroke:none
  style r2 fill:none,stroke:none

``` 

ok?

# how to put (user) and (ai) top most

"old" and "km"  side by side in the below

```mermaid
---
title: 4 obj

flowchart LR

    user[(User)]
    old[["Coding , Syntaxes , Debugging , Languages , DB , Networks , OS , Protocols ..." ]]
    km(("Management of **Knowledge**"))
    ai((AI))


  user <-.-> ai
  user --o km
  ai <---> km
  old --> user
```

# triangle: Human-Knowledge on top, za and AI at the bottom

Human-Knowledge is the apex; `za` and `AI` are the two base vertices.

Mermaid uses a layered (rank) layout, so *any* edge between `za` and `ai`
forces them onto different rows and you lose the triangle. Leave the base
edge out and the two apex-to-base edges alone give the triangle shape:

```mermaid
---
title: knowledge triangle
---
flowchart TB
    hk["Human-Knowledge"]
    hk --- za["za"]
    hk --- ai["AI"]
```

Padding the labels (`"...__ za __..."`) does not help — the stacking is
about *rank assignment*, not node size. An edge `za --- ai` means "ai is
one row below za", whatever width the boxes are.

To keep `za` and `AI` on the same row *and* draw a base line, wrap them in
a subgraph and link the apex to the **subgraph**, not to the inner nodes
(only one edge crosses the cluster boundary, so `direction LR` survives):

```mermaid
flowchart TB
    hk["Human-Knowledge"]
    hk --- base
    subgraph base [" "]
        direction LR
        za["za"] --- ai["AI"]
    end
    style base fill:none,stroke:none
```

Caveat: the apex connector stops at the (invisible) cluster boundary, so
there is a small gap above the `za`/`AI` row. Give `base` a visible border
if that bothers you, or drop the base edge and keep the clean version above.
