[I] Sankey nodeAlign examples have inconsistent titles and alignment behavior [echarts]
Manahil-Afzal opened a new issue, #21470:
URL: https://github.com/apache/echarts/issues/21470
### Version
5.5.2
### Link to Minimal Reproduction
https://echarts.apache.org/examples/en/editor.html?c=sankey-nodeAlign-left https://echarts.apache.org/examples/en/editor.html?c=sankey-nodeAlign-right
### Steps to Reproduce
1. Open the ECharts Official Editor for `sankey-nodeAlign-left` or `sankey-nodeAlign-right`.
2. Observe the chart title and node alignment.
3. Compare nodeAlign value in code vs. displayed title.
4. Notice the mismatch: right-aligned nodes are labeled as "Node Align Left" and left-aligned nodes are labeled as "Node Align Right".
### Current Behavior
- `sankey-nodeAlign-right` uses nodeAlign: "right" but title shows "Node Align Left".
- `sankey-nodeAlign-left` uses nodeAlign: "left" but title shows "Node Align Right".
- The visual alignment does not match the title or file name.
### Expected Behavior
- `sankey-nodeAlign-right` should have nodeAlign: "right" and title: "Node Align Right".
- `sankey-nodeAlign-left` should have nodeAlign: "left" and title: "Node Align Left".
- File name, title, and node alignment should be consistent.
### Environment
```markdown
- OS: Any (tested on Windows 10)
- Browser: Chrome 109
- Framework: None (pure JS/HTML)
```
### Any additional comments?
The Sankey nodeAlign demo examples currently violate their own semantic contract: the file name, chart title, and demonstrated behavior do not describe the same thing.
In particular:
sankey-nodeAlign-right:
nodeAlign: "right"
Title: “Node Align Left”
sankey-nodeAlign-left:
nodeAlign: "left"
Title: “Node Align Right”
Because these demos are frequently used as authoritative references when diagnosing Sankey layout behavior, this contradiction creates a false baseline for comparison. It becomes unclear whether observed alignment behavior is a rendering issue or simply an example mismatch.

Closing this issue because it belongs in the echarts-examples repository instead of the main repo.
