Chart Generation from SQL

Chart generation from SQL is the automatic conversion of query results into an appropriate visualization–choosing the right chart type, axes, and formatting without manual configuration.

Query results and charts are usually separated by tedium: export the rows, open a chart builder, pick a type, assign axes, fix the labels. Automatic chart generation collapses those steps–the system inspects the result's shape (a time column and a numeric column suggests a line chart; categories and counts suggest bars) and renders the visualization directly. The payoff is that visualization becomes the default rather than the extra effort, and trends that would hide in a number grid become visible immediately. It is a core piece of making data exploration fast enough that people keep exploring.

Fig — every answer ships with the tables, rows and SQL behind it.
