Python code

  • There is a starter code that correctly creates graphs in most cases. See here here
  • You need to define the function handler(df_list):
    • df_list is a list of pandas DataFrames df_list = [df1, df2, df3, ...]
    • It needs to return value in the form as below: 
      response = {
  'headers': {"Content-Type": "image/jpg"},
  'statusCode': 200,
  'body': body,
  'isBase64Encoded': True
}
