This example displays a simple record of two trees surveyed in Mui Shue Hang Park, Tai Wo, with accompanying position and altitude data. The visualization shows two schematic trees composed of geometric shapes, each represented as a group containing a brown rectangular trunk and a green elliptical crown. The code uses D3 v7 selection and SVG element creation to append and position these shapes. Specific attributes such as coordinates and fill colors are set directly on the rectangles and ellipses. Data is presented in an HTML list format with highlighted labels for each tree.
