<｜begin▁of▁sentence｜>### Instruction:
As an Event Coordinator responsible for organizing a technology conference, I have received a request to visually represent a directional network graph showcasing the connections between three key conference topics: "Data Security," "Artificial Intelligence," and "Blockchain Technology." I need to use the CairoArrowEdgeDrawer to create a graphical representation of the directed connections, illustrating the flow of information from "Data Security" to "Artificial Intelligence" and from "Artificial Intelligence" to "Blockchain Technology" with arrowed edges. This visual representation will help convey the interdependence and sequence of these pivotal topics to the conference attendees effectively.
### Response:
import igraph as ig
from igraph import plot

# Create a simple directed graph
g = ig.Graph(directed=True)
g.add_vertices(3)
g.add_edges([(0, 1), (1, 2)])

# Define visual style for the plot
visual_style = {'vertex_size': 20,'edge_curved': False,'edge_arrow_size': 1}

# Plot the graph
plot(g, **visual_style)
