Review Comment:
### Unsafe Dynamic Module Import <sub></sub>
<details>
<summary>Tell me more</summary>
###### What is the issue?
Dynamic require statement may fail if the locale doesn't have a
corresponding language file, and concatenating strings for module paths is
error-prone.
###### Why this matters
This can cause runtime crashes when an unsupported locale is selected, as
the require will fail to find the module.
###### Suggested change
Add error handling and validate supported locales:
```typescript
try {
const lang =
require(`echarts/lib/i18n/lang/${localeObj.toUpperCase()}`).default;
echarts.registerLocale(localeObj.toUpperCase(), lang);
} catch (e) {
console.warn(`Locale ${localeObj} not supported in ECharts`);
}
```

Review Comment:
### Missing locale state fallback <sub></sub>
<details>
<summary>Tell me more</summary>
###### What is the issue?
Optional chaining without fallback for potentially undefined locale state
###### Why this matters
If the state.common or locale is undefined, this will silently pass
undefined to locale operations, causing runtime errors in the subsequent
operations.
###### Suggested change
Add a fallback value when accessing the locale state:
```typescript
const localeObj = useSelector((state: ExplorePageState) =>
state?.common?.locale ?? 'en');
```

### Missing Locale Fallback <sub></sub>
<details>
<summary>Tell me more</summary>
###### What is the issue?
No null check or default value for locale before using it in string
operations and initialization.
###### Why this matters
If the locale is undefined or null, the subsequent toUpperCase() calls will
throw runtime errors.
###### Suggested change
Add a default value for locale:
```typescript
const localeObj = useSelector((state: ExplorePageState) =>
state?.common?.locale) ?? 'en';```
