Antv L7

What it does

When your agent uses it

• Create interactive maps with WebGL rendering
• Visualize geographic data (points
• Build location-based data dashboards
• Process and display GeoJSON

Example prompts

• “/antv-l7”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1场景初始化优先: 始终从创建 Scene 开始
2. 2数据格式规范: 优先使用 GeoJSON 标准格式
3. 3性能优先: 大数据量时使用数据过滤和聚合
4. 4渐进增强: 先实现基础功能，再添加交互和动画
5. 5错误处理: 添加事件监听和数据验证

What it can do on your machine

Read from SKILL.md and the folder at commit 6e3dbfe. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript and json).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Antv L7 loads about 1.4k tokens when it runs, and up to ~92k if it reads all its reference files. Until then it costs about 126 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~126

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~92k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Comprehensive guide for AntV L7 geospatial visualization library. Use when users need to: (1) Create interactive maps with WebGL rendering (2) Visualize geographic data (points, lines, polygons, heatmaps) (3) Build location-based data dashboards (4) Add map layers, interactions, or animations (5) Process and display GeoJSON, CSV, or other spatial data (6) Integrate maps with AMap (GaodeMap), Mapbox, Maplibre, or standalone L7 Map (7) Optimize performance for large-scale geographic datasets

import { Scene, PointLayer } from '@antv/l7';
import { GaodeMap } from '@antv/l7-maps';

// 1. 初始化场景
const scene = new Scene({
  id: 'map',
  map: new GaodeMap({
    center: [120.19, 30.26],
    zoom: 10,
    style: 'light',
  }),
});

// 2. 添加图层
scene.on('loaded', () => {
  const pointLayer = new PointLayer()
    .source(data, {
      parser: { type: 'json', x: 'lng', y: 'lat' },
    })
    .shape('circle')
    .size(10)
    .color('#5B8FF9');

  scene.addLayer(pointLayer);
});

1. 场景初始化 (Scene) → 2. 数据准备 → 3. 创建图层 (Layer) → 4. 添加交互 → 5. 优化性能

城市可视化 = scene + polygon + point + events + popup
轨迹动画 = scene + line + animation
热力分析 = scene + heatmap + data/json

  "point-layer": {

// 核心
