Notes:

觀察出圖的結果，您覺得哪裡還可以再調整，以提升視覺化呈現

尚未解決 ggsflabel 標站名的問題，台北等站因重疊問題未標出

補充說明程式碼撰寫問題，若出現錯誤訊息也請貼上

產圖的速度太慢了，希望能找到效能的癥結點，可能也需要簡化地理資料的細緻度才能加速。
Aesthetics must be either length 1 or the same as the data (1): label and geometry
1: 於 st_point_on_surface.sfc(data$geometry)： st_point_on_surface may not give correct results for longitude/latitude data
2: ggrepel: 17 unlabeled data points (too many overlaps). Consider increasing max.overlaps
