# GraphDataFrameBridge.jl

Tools for interoperability between DataFrame objects and LightGraphs and MetaGraphs objects.

## Examples:

```julia

julia> using DataFrames

julia> using GraphDataFrameBridge

julia> df = DataFrame(Dict("start" => ["a", "b", "a", "d"],

                           "finish" => ["b", "c", "e", "e"],

                           "weights" => 1:4,

                           "extras" => 5:8))

# Simple undirected MetaGraph

julia> mg = MetaGraph(df, :start, :finish)

{5, 4} undirected Int64 metagraph with Float64 weights defined by :weight (default weight 1.0)

julia> props(mg, 1)

Dict Symbol → Any with 1 entries

  :name → "a"

# Simple directed MetaDiGraph

julia> mdg = MetaDiGraph(df, :start, :finish)

{5, 4} directed Int64 metagraph with Float64 weights defined by :weight (default weight 1.0)

# MetaGraph with `weight` attribute set and

# `:extras` values stored as attributes.

julia> mgw = MetaGraph(df, :start, :finish,

                       weight=:weights,

                       edge_attributes=:extras)

{5, 4} undirected Int64 metagraph with Float64 weights defined by :weight (default weight 1.0)

julia> props(mgw, 1, 2)

Dict Symbol → Any with 2 entries

  :extras → 5

  :weight → 1

```

## Updating Release:

Note to self: update version in `Project.toml`, then comment on commit `@JuliaRegistrator register`
