Abscissa and ordinate a parametric equation. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical model or experiment (with any ordinates filling a role analogous to dependent variables). Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and
International Symposium on Graph Drawing times), and the United States (five times). A citation graph having vertices representing the papers in the 1994–2000 Graph Drawing symposia and having edges representing citations between these papers was made available as part of the graph drawing contest associated with the 2001 symposium. The largest connected component of this graph consists of 249 vertices and 642 edges; clustering analysis reveals several prominent subtopics within graph drawing that are more tightly connected, including three-dimensional graph drawing and orthogonal graph drawing. International Symposium on Graph Drawing The International Symposium on Graph Drawing (GD) is an annual academic conference in which researchers
