Chart Marker

What Problem Does This Solve? Clustering is limited to counts of features without the ability to visualize a second dimension within the data Why Use This Pattern? A common technique to avoid showing too many points on the map is clustering them into bubbles with numbers inside. This mechanism is effective to illustrate the amount […]

Spatial Filter

What Problem Does This Solve? Users are only interested in seeing features or results for a very specific region or area of interest. Why Use This Pattern? Location, location, location is not only the mantra in real estate but true for most consumer applications. People’s interest is many times constrained to a very specific geographic […]

Attribute Filter

Attribute Filter

What Problem Does This Solve? Users need to narrow a concrete set of features by its attributes. When to Use This Pattern Filtering is a common way to reduce the amount of features displayed on the map and/or a grid. Allowing users to progressively remove what they are not interested in will inadvertently leave them […]

Data Dimming

Data Dimming

What Problem Does This Solve? The map contains too many features so that it is difficult to identify them, distinguish them, pick out relationships, see patterns in the distribution. Why Use This Pattern? The same location might be occupied by multiple features of different types and therefore visually obscure their existence. Data Dimming helps highlighting […]

Extent-driven Content

Extent-driven Content

What Problem Does This Solve? A user wants to see points of interest within a given area as visually represented through the current map extent. Typically, the available options (results) update when the user changes the map extent through panning or zooming. When to Use This Pattern Sometimes called a ‘short list’ this pattern is […]

Flowmap

Flowmap

What Problem Does This Solve? Data visualization with straight or geodesic lines have visual limitations. When to Use This Pattern Illustrate connections between points and their associated flow of something. Examples of such can be supply chain apps that show the flow of goods between depots, air travel, migration behavior, the spread of diseases or […]

Data Ink Ratio

Data-ink ratio

WHAT The data-ink ratio pattern relates to the amount of ink used to provide useful information. It compares the amount of data versus the amount of ink, or pixels, used in the display. A well-designed app should aim for a high ratio of relevant to irrelevant information, or a high ratio of data to ink. […]
