URL: https://github.com/apache/echarts/pull/19519#issuecomment-2131318837
### 1. Summary of Changes
The pull request introduces support for Sankey chart datasets in the Apache
ECharts library. The changes include:
- A new helper function `createGraphDataFromDataset` to create graph data
from datasets.
- Modifications in `SankeySeries` to support the new dataset-based graph
creation.
- A new test file `dataset-sankey.html` to test the Sankey chart with
different dataset formats.
### 2. Issues, Bugs, or Typos
#### Issue 1: Unnecessary Concatenation in `prepareSeriesDataSchema`
- **Code:**
```typescript
if (zrUtil.indexOf(coordDimensions, 'value') < 0) {
coordDimensions.concat(['value']);
}
```
- **Improvement:**
```typescript
if (zrUtil.indexOf(coordDimensions, 'value') < 0) {
coordDimensions.push('value');
}
```
- **Reason:** `concat` does not modify the original array but returns a new
one. Use `push` to directly modify the array.
#### Issue 2: Inconsistent Formatting in Import Statements
- **Code:**
```typescript
import {LayoutRect} from '../../util/layout';
import {createTooltipMarkup} from '../../component/tooltip/tooltipMarkup';
```
- **Improvement:**
```typescript
import { LayoutRect } from '../../util/layout';
import { createTooltipMarkup } from
'../../component/tooltip/tooltipMarkup';
```
- **Reason:** Maintain consistent spacing for better readability.
### 3. General Review of Code Quality and Style
#### Code Quality
- **Modularity:** The code is well-modularized, with the new functionality
encapsulated in the `createGraphDataFromDataset` function.
- **Error Handling:** The function `throwError` is used to handle
unsupported dataset formats, which is good practice.
- **TypeScript:** Proper TypeScript types and interfaces are used, enhancing
code clarity and type safety.
#### Code Style
- **Consistency:** The code generally follows consistent formatting and
naming conventions.
- **Documentation:** The new function `createGraphDataFromDataset` is not
documented. Adding a JSDoc comment would improve code maintainability.
- **Test Coverage:** The new test file `dataset-sankey.html` is
comprehensive, covering various dataset formats.
### Summary
Overall, the code quality is good, with minor improvements suggested for
better performance and readability. The new functionality is well-integrated
and thoroughly tested.
