Who introduced the ashoka chakra in our national flag?

The Ashoka Chakra was introduced in the Indian national flag by the Flag Committee, which was headed by Pingali Venkayya. The chakra, a depiction of the Dharmachakra, symbolizes the eternal wheel of law and represents truth and righteousness. It was adopted on July 22, 1947, as part of the flag's design to reflect India's commitment to justice and moral authority.
