nuxt-model-graphs

Schema-driven charting for Nuxt 4, powered by ECharts. Define dimensions and measures once, pick a graph kind, and let the renderer derive the right series/axes (including 3D) with shared, typed models.

What’s inside

• Schema/selection-first API with typed helpers (ChartSchema, ChartSelection, GraphKind, etc.) exposed via #chart
• Single <ChartRenderer> that converts raw rows into the right series for line, bar, area, scatter, bar3d, or matrix heatmaps
• Auto-registered graph components and the bundled <VChart> plugin
• useChartExplorer composable for UI-driven dimension/measure selection
• Runtime config (graphs.defaultHeight) to control default renderer height

Install

pnpm add https://github.com/global-maxima/nuxt-model-graphs.git
# or npm / yarn equivalent

Enable the module:

export default defineNuxtConfig({
  modules: ['nuxt-model-graphs'],
  graphs: {
    defaultHeight: 256, // optional override
  },
})

Quick start

<script setup lang="ts">
import type { ChartSchema, ChartSelection, DataRow, GraphKind } from '#chart'

type Dim = 'month' | 'channel'
type Mea = 'revenue'

const schema: ChartSchema<Dim, Mea> = {
  dimensions: [
    { id: 'month', label: 'Month' },
    { id: 'channel', label: 'Channel' },
  ],
  measures: [{ id: 'revenue', label: 'Revenue' }],
}

const selection: ChartSelection<Dim, Mea> = {
  dimensions: ['month', 'channel'],
  measures: ['revenue'],
}

const data: DataRow<Dim, Mea>[] = [
  { month: 'Jan', channel: 'Web', revenue: 120 },
  { month: 'Jan', channel: 'Retail', revenue: 80 },
]

const graphKind: GraphKind = 'bar'
</script>

<template>
  <ChartRenderer
    :data="data"
    :schema="schema"
    :selection="selection"
    :graph-kind="graphKind"
    :encoding="{ showLegend: true }"
  />
</template>

Components (<LineGraph>, <BarGraph>, <ScatterPlot>, <BarGraph3D>, <MatrixGraph>) remain available if you want to pass pre-built chartData, but <ChartRenderer> is the primary entry point.

Interactive selection

const explorer = useChartExplorer(schema, {
  defaultDimensions: ['month'],
  defaultMeasures: ['revenue'],
  defaultGraphKind: 'line',
})

// explorer.selection, explorer.graphKind, explorer.availableGraphKinds, etc.

Bind explorer.selection and explorer.graphKind to <ChartRenderer> for a lightweight chart explorer UI.

Development
