Add quiver trace type for vector field visualization by degzhaus · Pull Request #7710 · plotly/plotly.js

This PR adds a new quiver trace type to Plotly.js for visualizing 2D vector fields using arrows.

Plotly.newPlot('div', [{
  type: 'quiver',
  x: [0, 1, 2],
  y: [0, 1, 2],
  u: [1, 0, -1],  // x-component of vectors
  v: [0, 1, 0],   // y-component of vectors
  sizemode: 'scaled',  // 'scaled' | 'absolute' | 'raw'
  sizeref: 0.5,
  anchor: 'tail',  // 'tail' | 'tip' | 'center'
  colorscale: 'Viridis',
  line: { width: 2 }
}]);
