This example demonstrates how SVG text elements can be positioned and anchored in different ways within a D3 v4 visualization. It shows three text strings placed at the same x-coordinate but with distinct text-anchor values (start, middle, end) and dx offsets, illustrating how alignment affects placement relative to the anchor point. The code also includes a simple circle with a CSS class that applies a hover effect, increasing its radius and stroke width. Using D3's selection and append methods, the visualization creates an SVG canvas and populates it with static text and a single interactive dot.
