New Chart Types
Users can now create 4 new chart types in the Seer Data Platform’s Insight Builder.
Sankey Chart:
A Sankey chart helps you visualise flow and relationships between categories, with the width of the paths representing the volume moving from one node to another.
Use a sankey chart when you want to
- Show participant journeys through a program, from entry to outcomes.
- Philanthropic or grant investments and how they translate into activities, outputs and longer-term outcomes.
- System-level flows such as referrals, reach or resource distribution.
- How datasets or initiatives align to frameworks, commitments or a Theory of Change.

Bar and Line Chart:
The Bar and Line Chart is a hybrid visualisation that combines bar and line series on the same X-axis. It’s designed to help compare two different measured quantities over time—each with its own independent Y-axis.
Use a bar and line chart when you want to
- Visualise two related metrics with different units or scales (e.g. number of young people participating in work readiness programs vs percentage decrease in contact with the justice system).
- Compare absolute values (bars) against trends or percentages (lines).
- Provide a clear, side-by-side view of how distinct measures behave in relation to the same categories or time intervals.

Vertical Biaxial Bar Chart:
A Vertical biaxial bar chart displays two different bar series on the same X-axis. It’s designed to help compare two different measured quantities over time—each with its own independent Y-axis.
Use a vertical biaxial bar chart when you want to
- Visualise two related metrics with different units or scales (e.g. number of participants vs average hours of engagement), using bars for both.
- Compare absolute values side by side while maintaining separate Y-axes for clarity.
- Provide a clear, direct comparison of how two distinct measures behave across the same categories or time intervals.

Single Stacked Bar Chart:
The Single stacked bar chart is a horizontal chart that shows how different values contribute to a total, all within a single stacked bar.
Use a Single stacked bar chart when you want to show the proportional breakdown of values in one group.
