DendroMap Explorer

DendroMap Explorer turns any hierarchy in your data into an interactive, drill-down tree — right inside your Tableau dashboard. Click a node to expand its children, follow one branch at a time or open several at once. Each card shows its value and share of the parent, so structure and magnitude read at a glance.

What you can do

• Drill down through any hierarchy — Region → Country → State → City, or whatever dimensions you choose.

• Compare branches — pin nodes to a comparison strip and read their values side by side.

• Surface outliers — group small items into an "Others" bucket and reveal more on demand.

• Read values your way — as a share of the parent, the level total, or the global total.

• Style it to your dashboard — set colors for positive and negative values and the card background, choose horizontal or vertical layout, and configure the default view once in edit mode.

Requirements

• Tableau Desktop, Server, or Cloud (Extensions API 1.6+)

• One worksheet with a dimension hierarchy and a measure

• Runs entirely client-side — no data leaves your dashboard, and the extension makes no external network calls.
