We call such drawings disk-link drawings. In this paper we focus on the case of constant edge-vertex resolution, namely ρ=1/2 (i.e., disks of unit diameter). ...
We study the algorithmic problem of computing drawings of graphs in which (i) each vertex is a disk with fixed radius ρ, (ii) each edge is a straight-line segment connecting the centers of the two disks ...
In relation to our work, they state that every 3-connected planar graph with n vertices admits a convex grid drawing with constant edge-vertex resolution in (3n − 7) × (3n − 7)/2 area. ...

We show that several types of graph drawing in the hyperbolic plane require features of the drawing to be separated from each other by sub-constant distances, distances so small that they can be accurately ...
Therefore, for these types of drawing, hyperbolic geometry provides no benefit over Euclidean graph drawing. ...
Grid graphs also obey similar bounds (Theorem 5). -Beyond planar graph drawing, every n-vertex graph has a Euclidean drawing with unit vertex-vertex resolution and angular resolution Θ(1/n). ...

We present the first smooth tradeoff between the area and angular resolution for 2-bend polyline drawings of any given planar graph. ...
Specifically, for any given n-vertex triangulation, our algorithm computes a drawing with angular resolution r/d(v) at each vertex v, and area f (n, r), for any r ∈ (0, 1], where d(v) denotes the degree ...
Allowing bends helps both to reduce area and to improve angular resolution, e.g., given an n-vertex planar graph with maximum degree ∆, one can construct a 3-bend polyline drawing with 2/∆ radians of resolution ...
