Trend analysis, or a time series graph, is helpful when you want to explore what's been happening in your data over a period of time.
There are a few magic words that you can use in your question to trigger Anna to respond with a trend analysis, like:
You can ask Anna a simple question, like "Anna, show me sales by department"
Or, you can make your question a bit more complex by filtering for results only for a particular segment.
You can even add in a time period to your question!
