EnvCanViz (Minimal M1)

A tiny Python script that reads an Environment Canada CSV you downloaded and lets you:

1. See the available columns.
2. Print the first N values from a chosen column.

This is the first milestone (M1). Future milestones will add cleaning, plotting, and summaries.

Features (current)
