Data-driven graphics connect dataset values to visual structure, such as rectangle lengths and heights in a histogram or bars in a chart. section 1.1.3
D3.js builds these graphics explicitly: load data, format values, inspect characteristics, combine visualization functions, and add interaction. section 1.1.3
A practical construction workflow includes:
- Load CSV or JSON data with the d3-fetch module. section 1.1.3
- Format numbers and dates, then identify useful characteristics such as minimum and maximum values. section 1.1.3
- Use scales to calculate visual dimensions and functions to create marks and axes. section 1.1.3
- Listen for mouse events to support filtering or zooming. section 1.1.3
