Clarify how to visualize change over a time range before building a trend. Use whenever the user asks how much something changed, grew, dropped, improved, or regressed between two points or periods — "how much did X change from A to B", "before vs after", "start vs end", "week over week", "compare this month to last", "change over time" — or mentions a "slope chart" / "slopegraph". Two readings of "change" need different charts: the whole trend (a line, every interval) versus just the two endpoints (a slope, start vs end). Ask which they want, then render it. Not for choosing a saved insight ChartDisplayType in the insight editor.

"How did X change between A and B?" is ambiguous. Two charts answer two different questions, so clarify before you build unless the user already named one:
- Change over time (line) — the value at every interval across the range. Shows the path: dips, spikes, when it moved. This is the default trend.
- Start vs end (slope) — only the first and last point, one line per series connecting them. Shows the net change and, across many series, which rose, which fell, and any rank flips — without the noise of the path between.
When the request could be either, ask a short either/or, e.g.:
Do you want to see how it moved across the whole period (a line chart), or just
