Pokédex Type Treemap

What This Shows

• What the chart shows: Pokémon grouped first by primary type, then by evolution family, with individual species details available inside the interface.
• Who it is for: Pokémon fans, game-data explorers, collectors, designers, and anyone who likes seeing a Pokédex reorganized as a visual system.
• Why it is interesting: it turns type balance, evolution families, species counts, and base stat totals into a map you can browse instead of a flat list.
• Best way to use it: click a type block, drill into an evolution family, then select a Pokémon from the treemap or Index to inspect its Dex-style panel.

What Is A Treemap?

A treemap is a space-filling chart that turns categories into nested rectangles. Bigger rectangles represent larger values, while smaller rectangles fit inside their parent group.

For a Pokédex-style visualization, that means Pokémon can be grouped by primary type, then evolution family, then individual species. It is a compact way to compare categories that would be harder to scan in a normal table.

What The Pokémon Type Data Reveals

The published dataset contains 1,025 Pokémon species across 9 generations and 18 primary-type groups. These findings describe the static dataset used by this visualization, with each species counted once in its primary-type block.

How To Use The Visualization

• Search Pokémon: use the search box to find Pokémon, type names, or role text across the treemap and Index.
• Click type blocks: select a primary type to zoom into its evolution families.
• Click evolution families: drill from a family block into individual species tiles.
• Select Pokémon: click a species tile or Index card to open its Dex-style entry, stats, abilities, and available move details.
• Change sorting: sort the Index by featured order, power high-to-low, or name A-Z.
• Change sizing: switch the treemap between base-stat sizing and species-count sizing.
• Navigate back: use the Back button or breadcrumb pills to move up from Pokémon to family, type, or all types.
• Use the D-pad controls: move focus around the treemap with the on-screen directional pad.

Why This Matters For Fans

Pokémon fans often know the Pokédex through lists, stats pages, team builders, and type charts. This project gives the same world a different shape: a visual territory map of types, families, and species.

That makes it useful for pattern spotting, team-building inspiration, design comparison, collecting conversations, or just browsing Pokémon data in a more tactile way.

Methodology And Data Note

The visualization's primary source is the versioned static dataset generated from PokéAPI species, default-variety, and evolution-chain resources. The interface groups Pokémon by primary type and evolution family, then displays species-level details where the data exists. The counts shown on this landing page are calculated from the canonical snapshot containing 1,025 species records.

Dataset version: 1.0.0. Generated: May 25, 2026. Provenance reviewed: August 10, 2026. The canonical package records its sources, transformations, coverage, limitations, modeled fields, schema, and verification rules in the repository.

Review the sources: PokéAPI documentation, dataset metadata and provenance, and the machine-readable schema.

Names, types, generation assignments, six base stats, abilities, evolution-chain relationships, selected English flavor text, and artwork references originate from PokéAPI data. Base-stat totals, normalized display labels, evolution-family labels, and aggregate counts are calculated transformations.

Presentation-model warning: the card-style attack power, attack type, and explanatory text shown in the interface are visualization fields generated for display. They are not official move power, official move type, official descriptions, legality guidance, or competitive rankings.

Known limitations: the snapshot ends at National Pokédex number 1,025; alternate forms are not separate records; type grouping uses primary type; and selected flavor text is not a complete game-by-game history. Verify formal or competitive data needs against official game resources or dedicated databases. Interpret tile size as a visualization setting, not an official importance ranking.
