title: Generating the function of the plane/surface that a given set of coordinates lie on
body: <p>This is something related with Mathematics as well. But this is useful in computing as well.</p>
  
  <p>Lets say you have 10 coordinates. (x1,y1)(x2,y2)..... in 2D Space. (i.e on a X-Y Plane). Can we find a single smooth curve going across the each coordinate. </p>
  
  <p>While expanding the question, If the space is 3D, then can we find an equation of a smooth surface that going across a given set of spacial coordinates?</p>
  
  <p>Are there any Libraries (Any language) \ tools to perform such calculations?</p>
