A dashboard component that displays hierarchical data as proportionally sized, colour-coded tiles. A treemap is a chart where larger values occupy more area and groups can contain smaller groups.

Use it for market maps, portfolio composition, sector groupings, heatmaps, tree charts, and other data grouped into nested categories.

It makes relative size, grouping, and a second measure such as change or category visible in one chart.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00178	$0.01500
Opus 5.5	$0.00071	$0.00600
Sonnet 5.5	$0.00036	$0.00300
Haiku 4.5	$0.00018	$0.00150

Security

Grade A, and why

kx-heatmap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

KX Heatmap (Treemap) Component

Also read kx-dashboard-core for: envelope, screen/widget wrapper, data sources, ViewState, binding patterns, actions, notifications, and the pre-flight checklist.

key: "Heatmap" · definitionId: "5" · componentName: "Treemap" · version: "v2.3.0.1"

A proportional tile (treemap) visualisation. Tile area is proportional to a size column; tile colour is driven by a separate colour column or a fixed palette.

This skill uses progressive disclosure: the identity, hazards, workflow, and output checklist are here; the bulky component JSON, per-section field tables, and worked patterns live in reference/. Read only the reference file relevant to your current step.

Reference Files

File	Read it when you need…
reference/component-schema.md	The full component JSON plus the per-section field tables — `Basics`, `Data[]` layer definitions and `HighlightRules`, `ColorPalette`, `NodeLabel`, `GroupBy`, `Tooltip`, and `Animation`.
reference/examples.md	Copy-ready patterns — market map (size by market cap, colour by % change), sector-grouped treemap, and fixed-colour portfolio composition.

⚠️ Hazards — Read First

key is "Heatmap" but it renders a Treemap — the component is named Treemap internally (componentName: "Treemap") and uses ECharts treemap. There is no traditional heatmap matrix; this is a proportional tile/treemap component.
Data[] is an array of layer objects, not a data source — Basics.Data is the data source binding. Data[] defines how to use columns from that source (Column = display/label column, Size = tile size column, Color = colour column). At minimum one Data[] entry is required.
Basics.SelectedAttr specifies which column is published on click — Selected receives the value of SelectedAttr column from the clicked node. If SelectedAttr is blank, nothing is published to Selected.
ColorType: "Scaled" or "Gradient" uses the Color column — other types (Fixed, Iterative, Iterative Children) use FixedColor or cycle through ColorScheme.
GroupBy.UseGroupBy: true creates a hierarchical treemap — GroupByColumns defines the parent group column. Each group gets a header bar; ShowHeader: true is required to see the label.
NodeLabel.customLabel is plain-text only — it is a Handlebars template rendered as canvas text by ECharts. HTML elements (<br>, <b>, <span>, etc.) are not rendered; they appear as literal characters. Use a plain separator such as a space or | between values (e.g., "{{sym}} | {{pctChange}}%").
version in the JSON must be "v2.3.0.1" — this is the current version applied after all upgrades.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kx-heatmap is a skill published in the GitHub repository KxSystems/kx-skills (22 stars, last pushed 22d ago), licensed Apache-2.0. It adds 178 tokens to every session and 1,500 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
