Improving Your Data Visualization Flow with Altair and Vega-Lite
Improving Your Data Visualization Flow with Altair and Vega-Lite


Your boss just asked you to ""whip up"" a chart for a stakeholder review in an hour. You know you made that really slick visual a couple months ago, it would be a perfect fit for your current dataset. However, you can only find the final PNG, not the original notebook with your carefully crafted matplotlib magic. After a quarter hour's search, you give up and start pummeling Stack Overflow, hoping to find that thread that had all the answers last time...

Sound familiar? If you're a Pythonista whose data visualization process could use a makeover, then this talk is for you. We'll identify the elements of an effective data visualization flow and explore how the Altair and Vega-Lite stack can improve your own data visualization practice.

The visualization demonstration will feature data sourced from S&P Global's curated content sets, now available through the Snowflake Cloud Data Platform.
