@ComputerScientist-01 @mostafagafer if you found the solution please share . I am having the same issue.

[ComputerScientist-01]

@puranjay123 no solution has been found yet

[puranjay123]

@ComputerScientist-01 they have changed the name of the data values so we need to change the name of the values and then it will work.

Modified the code to fit the new data model from CoinMarketCap. The main changes are in the load_data function. Verified the code in the latest streamlit version.

@ComputerScientist-01 they have changed the name of the data values so we need to change the name of the values and then it will work.

can you share the source code for this please
