Enhance Visualization by Highlighting Vertex Radii

The current visualization tool requires an enhancement to include the highlighting of Vertex Radii. This enhancement aims to provide a more informative and interactive visualization.

Features to Implement:

Display Vertex Radii as Spheres: Vertex radii should be visually represented as spheres with their centers located at their respective vertices. Each sphere's size should correspond to the radius of the associated vertex.
Selectable Single-Target Vertex: Users should be able to interactively select a single vertex. Upon selection, the chosen vertex will be highlighted, making it clear which vertex the user is working with.
Display Selected Vertex Radius: When a vertex is selected, its radius should be displayed as a numerical value. This provides users with immediate feedback on the radius value for the selected vertex.
Radius Adjustment Controls: Users should have the ability to adjust the radius of the selected vertex interactively. This can be achieved through both a slider and a numerical input field. The slider allows for quick adjustments, while the input field allows for precise radius values.
Export Function: Implement an export function that enables users to save any changes made to the vertex radii. This feature ensures that modifications to the radii can be retained for future reference or analysis.

Expected Outcome: These enhancements will result in a more interactive and informative visualization tool, allowing users to explore and manipulate vertex radii with ease.
