What problem does it solve?

Creating custom, interactive data visualizations with D3.js can be complex, requiring deep knowledge of SVG, data binding, and animation. This Skill simplifies D3.js development, providing guidance, templates, and best practices for building powerful and engaging data visualizations, from simple charts to complex network graphs.

Core Features & Use Cases

• Chart Generation: Create various chart types (bar, line, scatter, pie) with interactive elements.
• Data Transformation: Prepare and bind data to SVG elements for dynamic visualization.
• Advanced Patterns: Implement complex layouts, animations, and custom interactions.
• Use Case: You need to visualize real-time sensor data on a dashboard. Use this Skill to generate a dynamic line chart template, bind your data to it, and add interactive features like tooltips and zooming, providing clear insights to users.

Quick Start

Example: Basic D3.js bar chart setup (HTML/JS)

<div id="chart"></div>

<script src="https://d3js.org/d3.v7.min.js"></script>

<script>

const data = [10, 20, 30, 40, 50];

const svg = d3.select("#chart")

.append("svg")

.attr("width", 300)

.attr("height", 150);

svg.selectAll("rect")

.data(data)

.enter()

.append("rect")

.attr("x", (d, i) => i * 60)

.attr("y", d => 150 - d * 2)

.attr("width", 50)

.attr("height", d => d * 2)

.attr("fill", "steelblue");

</script>
