The essentials: datasette-agent-charts 0.1a1 brings Observable Plot integration with automatic color mapping by magnitude, categorical color schemes, and interactive tooltips for bar and waffle charts.
The datasette-agent-charts project has been released in version 0.1a1 and extends Datasette Agent with Observable Plot charts featuring interactive tooltips and improved color management.
With the first alpha version 0.1a1, datasette-agent-charts is enhanced with Observable Plot charts. The solution enables visual representation of database queries via Datasette Agent. The new functionality includes automatic color management: bar and waffle charts without an explicit color column receive sequential coloring based on the magnitude of values. Columns with text values use the categorical Observable10 color scheme.
From a security perspective, the version now performs a check before executing a query to verify that the execute-sql permission is present. This restricts access to SQL queries according to Datasette permissions. A bug in waffle charts (waffleY) that were not correctly described to the Agent has also been fixed.
User interaction is enhanced through interactive tooltips that display additional information when hovering over chart elements. As an alpha release, the version should be used with the usual limitations for pre-release versions.
