"Chord diagram links Chinese provinces grouped into East, Center, West, and North East regions. Chord width indicates connection magnitude and arrowheads indicate direction. The thickest chords originate from Sichuan and central provinces, including Henan, Hunan, and Anhui, and point towards eastern provinces, particularly Guangdong, Jiangsu, and Zhejiang. Numerous thinner connections link other provinces."
