This bar chart displays monthly fire occurrences in California, revealing a clear seasonal pattern with peak incidents in July (391 fires) and lowest counts during winter months. The visualization aggregates wildfire records from a CSV dataset loaded via `d3.csv`, then uses `d3.rollup` to count occurrences per month and `d3.scaleBand`/`d3.scaleLinear` for positioning. Bars are rendered as SVG rectangles with hover effects changing fill color to orange. Axis labels and count annotations are added via D3’s selection methods.

This template should work extremely well as a starting point for AI-driven iteration.

Iris Dataset Visualization with D3.js

This project demonstrates how to create a scatter plot visualization of the classic Iris dataset using D3.js, a powerful JavaScript library for creating data visualizations in a web browser. It provi

What is D3?

D3 (Data-Driven Documents) is a JavaScript library for producing dynamic, interactive data visualizations in web browsers. It uses HTML, SVG, and CSS to bring data to life.

About This Project

This visualization shows the famous Iris flower dataset, displaying the relationship between sepal length and sepal width across different iris species. Each point represents a flower, colored by spec

How This Works

The Code Structure

This project is organized into several files, each with a specific purpose:

  • index.js: The main entry point that loads data and orchestrates rendering
  • data.js: Handles loading and formatting the Iris dataset
  • renderSVG.js: Creates and configures the SVG container
  • renderScatterPlot.js: Creates the scatter plot visualization
  • observeDimensions.js: Makes the visualization responsive

Key D3 Concepts Used

  1. Data Loading: Using d3.csv() to fetch and parse CSV data
  2. Scales: Converting data values to visual properties (position, color)
  3. Axes: Creating readable reference lines and labels
  4. Data Joins: The pattern selection.data().join() to connect data with visual elements
  5. Transitions & Animations: Smooth updates when data or dimensions change
