Cycling infrastructure
-
Copenhagen is renowned as one of the world's most bicycle-friendly cities, with extensive cycling infrastructure
- serving hundreds of thousands of daily cyclists. The city's bicycle parking facilities are strategically located
- throughout the urban area to support this sustainable transportation network.
-
Explore the map below to discover bicycle parking locations across Copenhagen, including capacity information
- and geographic distribution patterns.
+
+
Where the bikes go
+
4,390 municipal bicycle racks, each with its capacity, street address and city district. Capacity
+ is the number the rack was built for, so the map reads as supply rather than as points.
+
-
Public libraries
-
Copenhagen's public library system serves as a cornerstone of community life, providing free access to
- knowledge, culture, and digital resources. From the iconic central library to neighborhood branches,
- these facilities support learning, creativity, and social connection across all city districts.
-
Use the interactive map below to locate libraries throughout Copenhagen and discover their unique
- characteristics and services.
+
+
The branch network
+
Nineteen public libraries, each with its address, postal district, contact address and its page on
+ the city's library site. Open a branch to follow the link out.

Nine facility types from Copenhagen's open data, imported from CSV and given coordinates, so every
+ one of them lands on a map. The chart below counts them by type; the containers hold the records.

Category analysis
-
Product categories represent different market segments with distinct characteristics and performance.
- Analyzing category-level metrics helps identify portfolio strengths, diversification opportunities, and inventory priorities.
+
+
Product categories
+
The segments the catalogue is organised into — beverages, condiments, produce and the rest.
+ Open one to see the products it holds.
+
+
+
+
Where the money is
+
Each category is a market segment with its own performance. Revenue first, then the spread of
+ products behind it.
+
-
Product distribution
-
Understanding how products are distributed across categories reveals portfolio balance and potential gaps.
- Categories with more products may indicate core competencies or simply broader product lines.
+
+
Portfolio balance
+
Revenue and range don't always line up. A category can earn well on few lines, or spread wide
+ and earn little — the gap between the two charts is where the portfolio questions are.

The account book
+
Every company Northwind sells to, with its contact details and address. Open an account to see
+ its full order history.
+
-
Geographic distribution
-
Our customer base spans multiple countries, with varying levels of market penetration.
- Understanding geographic concentration helps guide expansion efforts and resource allocation.
+
+
Geographic distribution
+
The customer base spans many countries at very different depths. Where the accounts cluster is

-
Customer portfolio
-
Browse individual customer records below to view detailed order history, contact information,
- and relationship details. Each customer profile provides insights into purchasing behavior and account status.

SKOS concepts
-
Concepts are the fundamental building blocks of the UNESCO Thesaurus vocabulary. Each concept represents
- a distinct unit of thought or terminology, enriched with multilingual labels, definitions, and semantic relationships.
-
SKOS (Simple Knowledge Organization System) relationships connect concepts through:
-
- Broader/Narrower - Hierarchical relationships forming taxonomic structuresRelated - Associative relationships between concepts in the same domainExact/Close/Related Matches - Mappings to concepts in external vocabularies
+
+
The concepts
+
Every concept carries its labels in each language the thesaurus publishes, and its place in the
+ hierarchy. Open one to get the concept tree beside it — that column is the taxonomy editor package's,
+ not the platform's.
+
+
SKOS connects concepts three ways:
+
+
+ Hierarchical Associative Matches
+
+
Broader/Narrower relationships form the taxonomic backbone: every concept links up to more general concepts and down to more specific ones, and parallax
+ navigation follows those links in either direction.
+
+
+
Related relationships associate concepts across the hierarchy — concepts in the same domain that are neither broader nor narrower than each other.
+
+
+
Exact, close, broad and related matches map concepts to external vocabularies. The Northwind Traders demo maps its product categories here: its
+ Beverages category is a skos:closeMatch of this thesaurus's Beverages concept, Condiments a
+ skos:broadMatch of Food , and Confections a skos:relatedMatch of Sugar .
+
+
Browse the concepts below and use parallax navigation to explore their rich semantic network.
