Show me a bar chart for what are the different transaction types, and how many transactions of each have taken place?, and sort by the total number in ascending please.
SELECT transaction_type, COUNT(*) FROM Financial_Transactions GROUP BY transaction_type ORDER BY COUNT(*)
SELECT "transaction_type", COUNT(*) FROM "Financial_Transactions" GROUP BY "transaction_type" ORDER BY COUNT(*)
