FileNotFoundError

[xiashuqin89]

when i try to run example code below:

# diagram.py
from diagrams import Diagram
from diagrams.aws.compute import EC2
from diagrams.aws.database import RDS
from diagrams.aws.network import ELB

with Diagram("Web Service", show=False):
    ELB("lb") >> EC2("web") >> RDS("userdb")

It output exception info like this:

raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: PosixPath('dot'): PosixPath('dot')

and it seems not generate the png, but just a simple file contain some config info:

digraph "Web Service" {
    graph [fontcolor="#2D3436" fontname="Sans-Serif" fontsize=15 label="Web Service" nodesep=0.60 pad=2.0 rankdir=LR ranksep=0.75 splines=ortho]
    node [fixedsize=true fontcolor="#2D3436" fontname="Sans-Serif" fontsize=13 height=1.4 imagescale=true labelloc=b shape=box style=rounded width=1.4]
