How to Build a Custom Chart Plugin for Apache Superset 4.x

Apache Superset ships with more than fifty chart types, and for most dashboards, that is plenty. But what happens when you need something more specific—a bullet chart against a target band, a Sankey with a custom node order, a map layer the built-in deck.gl charts do not offer, or a KPI tile that colours itself against three thresholds instead of one?

At that point, you have two options: bend an existing chart until it almost fits, or build a plugin that fits your needs. Plugins are how Superset itself is built.

Every chart in the Explore view, from the humble table to the ECharts time series, is a plugin registered through the same ChartPlugin API you are about to use. A custom plugin is not second-class. It gets the same query layer, the same control panel framework, the same dashboard filters and cross-filters, and the same theming.

This guide builds a small but complete plugin for Superset 4.x. The chart is deliberately simple: a bar per category with a configurable highlight threshold, keeping the focus on the plugin mechanics. Once the plumbing is in place, swap the rendering for ECharts, D3, or deck.gl.
