Add Support for Velocity Arrows in Scatter (2D and 3D) Graphs

[AlmogHadad]

I propose adding a feature to the scatter and scatter3d graph types in Plotly to support velocity arrows. This feature would allow users to display directional arrows, enhancing data visualization for applications that involve vector fields, velocities, forces, or any data represented by direction and magnitude.
