Support for BigInt, BigDecimal datatypes #65
Description
Describe the bug
Datatypes such as BigInt, BigDecimal could not be represented in a graphical format. When I'm trying to integrate various graphs with values such as BigInt from the graphQL data sources. The error shows as "no graphable fields " or "no data". Below is a sample output from a datasource playground.
Below is the response from Query inspector
Expected behavior
Values of datatypes such as BigInt and BigDecimal fetched from a graphQL to be represented in the graphs.
