The Problem
When looking through a set of papers, e.g. when deciding on who should get a faculty position, people look at very coarse metrics, e.g. the citation count for a paper and the h-index of an author.
But these metrics don’t tell the whole story…
For each paper, our system has:
1) every reference with its citation count; and
2) every citation with its respective citation count,
The Problem
But the only metric ever really used to evaluate a paper is its citation count.
But it’s difficult to see the importance of papers citing this paper.
And it’s difficult to see the relative importance of a paper within its field (consider the importance of references too).
The Problem
Representing all of the information just as a number would remove information.
Our goal is to provide more information…visually.
The Problem
The visualization needs to encode:
1) The distribution of references and citations over time; 2) The number of citations for everything; 3) Encode self citations; and 4) Allow for extension (e.g. add data).
Encoding Requirements
The Problem
Also, we wished to create a design that could be used in a number of different contexts, including:
1) in a detailed view; 2) as a glyph; and 3) as a summary for an author or research field.

the impact graph
1) Plot the paper by its date of publication and citation count.
2) Plot all the references by their date and citation count.

4) Plot the citation momentum graph. e.g. aggregation of number of citations in a year.
