superset可视化具体操作步骤

查询语句

SELECT target AS target,
       source AS source,
                 count(*) AS count
FROM
  (SELECT source AS source,
                    target AS target,
                    SUM(value) AS sum__value
   FROM energy
   GROUP BY source,
            target
   ORDER BY sum__value DESC
   LIMIT 5000) AS expr_qry
GROUP BY target,
         source
ORDER BY count DESC
LIMIT 1000;

运行sql以后选择下方的Explore:
