This example visualizes a survey-like question, "DO YOU FEEL THE HEAT?", presented as a horizontal gradient bar with numeric endpoints (1 to 5) and a central line marker. The SVG drawing uses embedded CSS classes and a linear gradient definition to style the graphic. The visualization is embedded in an HTML page that also loads a Roboto font and an external Observable notebook iframe. The rendering relies on SVG elements like `<rect>`, `<line>`, and `<text>` with custom styling, while the iframe fetches data from Observable. The static SVG structure is fixed, with no interactive or dynamic behavior.
