What’s a librarian to do?

• Dream up ideas

• Use the data

Temporal data

Types of visualizations

Time-Series Plot Histogram Stacked graph Burst Detection (see visualization)

What to visualize The increase in the number of

citations for a specific publication over time

Number of new collaborators participating in a specific program

The amount of funding provided to an organization or researcher (see visualization)

13

Geospatial Data

Types of visualizations

Proportional Symbol Map Choropleth Maps (see visualization)

What to visualize The location (state/country) of

researchers, experts, or collaborators

The amount of funding on specific topic by geographical area

The location of authors who have cited, viewed, or downloaded a particular publication or work (see visualization)

Topical Data

Types of visualizations

Cross Maps Wordle Topic Bursts (see

visualization)

What to visualize Word co-occurrence on a

single document, book or other text-based research output combined with burst detection (see visualization)
