Pseudo Viz Radar Chart
This pseudo visualization demonstrates a radar chart for a single data point, Singapore, with values across four categories: CEI, GCI, NCSI, and DDL. The example shows how modular code functions in `d3.lineRadial` to draw the blue radar path, `circle` elements to mark data points, and SVG `line` and `text` elements to render the gray axes and category labels. The `d3.scaleLinear` maps values from 0 to 25 across five levels. The hue function redundantly adds a red fill, showcasing the composition of overlapping shapes in a modular structure.
AI-generated descriptionA demonstration of basic D3 usage to implement the concept of Marks and Channels. Includes usage of:
- Point Marks by X, Y, Size
- Line mark varying in length
- Scaling factors
- SVG Rectangles
selection.each()- SVG Path Elements
d3.symbol()- SVG attributes
transformandfill - D3 Color Schemes
- JavaScript Modules
