About

This skill generates D3.js visualizations for creating complex, interactive charts and graphs like network diagrams, tree maps, and geographic maps. It's ideal when you need more advanced customization than basic charting libraries offer, supporting features like zooming, tooltips, and smooth animations. Use it for building sophisticated, custom data visualizations directly within your development workflow.

D3.js Visualization Skill

D3.jsを使った高度なデータ可視化を生成するスキルです。

概要

D3.jsで複雑で美しいデータ可視化を作成します。Chart.jsより高度なカスタマイズが可能です。

主な機能

多様なチャート: ネットワーク図、ツリーマップ、サンキー図等
インタラクティブ: ズーム、ドラッグ、ツールチップ
アニメーション: スムーズなトランジション
地理データ: 地図、コロプレス図
階層データ: ツリー、パックレイアウト
時系列: ライン、エリアチャート

使用方法

以下のデータでD3.jsネットワーク図を作成：
ノード: A, B, C, D
リンク: A-B, B-C, C-D, D-A

可視化例

ネットワーク図（Force-Directed Graph）

<!DOCTYPE html>

<head>
  <script src="https://d3js.org/d3.v7.min.js"></script>
  <style>
    .node { fill: #69b3a2; stroke: #fff; stroke-width: 2px; }
    .link { stroke: #999; stroke-opacity: 0.6; }
  </style>
</head>
<body>
  <svg id="graph" width="800" height="600"></svg>
  <script>
    const data = {
      nodes: [
        {id: "A"}, {id: "B"}, {id: "C"}, {id: "D"}
      ],
      links: [
        {source: "A", target: "B"},
        {source: "B", target: "C"},
        {source: "C", target: "D"},
        {source: "D", target: "A"}
      ]
    };

    const svg = d3.select("#graph");
    const width = +svg.attr("width");
    const height = +svg.attr("height");

    const simulation = d3.forceSimulation(data.nodes)
      .force("link", d3.forceLink(data.links).id(d => d.id))
      .force("charge", d3.forceManyBody().strength(-400))
      .force("center", d3.forceCenter(width / 2, height / 2));

    const link = svg.append("g")
      .selectAll("line")
      .data(data.links)
      .join("line")
      .attr("class", "link");

    const node = svg.append("g")
      .selectAll("circle")
      .data(data.nodes)
      .join("circle")
      .attr("class", "node")
      .attr("r", 20)
      .call(d3.drag()
        .on("start", dragstarted)
        .on("drag", dragged)
        .on("end", dragended));

    simulation.on("tick", () => {
      link
        .attr("x1", d => d.source.x)
        .attr("y1", d => d.source.y)
        .attr("x2", d => d.target.x)
        .attr("y2", d => d.target.y);

      node
        .attr("cx", d => d.x)
        .attr("cy", d => d.y);
    });

    function dragstarted(event, d) {
      if (!event.active) simulation.alphaTarget(0.3).restart();
      d.fx = d.x;
      d.fy = d.y;
    }

    function dragged(event, d) {
      d.fx = event.x;
      d.fy = event.y;
    }

    function dragended(event, d) {

      d.fx = null;
      d.fy = null;
    }
  </script>
</body>
</html>

ツリーマップ

const data = {
  name: "root",
  children: [
    {name: "A", value: 100},
    {name: "B", value: 200},
    {name: "C", value: 150}
  ]
};

const width = 800;
const height = 600;

const treemap = d3.treemap()
  .size([width, height])
  .padding(2);

const root = d3.hierarchy(data)
  .sum(d => d.value);

treemap(root);

const svg = d3.select("body")
  .append("svg")
  .attr("width", width)
  .attr("height", height);

svg.selectAll("rect")
  .data(root.leaves())
  .join("rect")
  .attr("x", d => d.x0)
  .attr("y", d => d.y0)
  .attr("width", d => d.x1 - d.x0)
  .attr("height", d => d.y1 - d.y0)
  .attr("fill", "#69b3a2")
  .attr("stroke", "white");
