A bar chart showing the number of flights with price higher than 300 for each destination city, could you display in descending by the x-axis?
SELECT destination, COUNT(destination) FROM flight WHERE price > 300 GROUP BY destination ORDER BY destination DESC
SELECT "destination", COUNT("destination") FROM "flight" WHERE "price" > 300 GROUP BY "destination" ORDER BY "destination" DESC
