scientific research can be distinguished in the
context of the mentioned topic. Some scientists
deal with the conceptual aspects of data
journalism, developing theoretical approaches
and studying the conceptual apparatus of the
principal terms used in the direction mentioned
above, as well as consider the history of the
formation and development of data journalism
(Paraise & Dagiral, 2012; Coddington, 2015;
Howard, 2014; Royal & Blasingame, 2015;
Borges-Rey, 2016; Gray, Bounegru &
Chambers, 2012; Weber & Rall, 2012;
Medvedeva, 2020; Bidzilya & Kravets, 2019
Polyuga, 2019; Hannaford, 2015 ).
The second group of scientific investigations is
aimed at researching journalists' work as data
journalism subjects. Within this direction, the
professional profile of a journalist is considered,
and his "hard" and "soft" skills, methods of
software application, and the need for a team of
analysts and programmers are studied (Tabary et
al., 2016; Appelgren & Nygren, 2014; Royal,
2010; Weber & Rall, 2016; Paraise & Dagiral,
2012; De-Maeyer et al., 2015; Fink & Anderson,
2015; Uskali & Kuutti, 2015; Hermida & Young,
2017).
The third and most significant group of works
analyzes content available in media practice.
Such studies focus on data collection, analysis,
processing, and visualization features. At the
same time, scientists pay special attention to
solving practical problems related to the
typology, quality, quantity, interactivity, and
functionality of visual objects in data journalism
(Knight, 2015; Nguyen, 2017; Loosen et al.,
2020; Hamilton, 2016; Flew et al., 2012; Cohen
et al., 2011; Medvedeva, 2020; Lichenko, 2018).
It is worth noting that the views of scientists on
the definition of the concept of "data journalism"
coincide. For example, H. Hamilton (2016) and
S. Sunne (2016) believe that data journalism is
collecting, cleaning, organizing, analyzing,
visualizing, and publishing data. L. Rinsdorf and
R. Boers (2016) consider data journalism as a
process (analysis, collection, and processing of
information) and a product (the result of which is
journalistic material – text and visualization) at
the same time. So, scientists identify data
visualization in journalism as a critical element
of information design, which allows consumers
to understand the material. Note that "data
journalism" cannot be equated with "data
visualization"; visualization exists as an
independent phenomenon, but data journalism
often uses visualization as a storytelling tool.
"Data Visualization," according to R. Borgo et al.
(2013) and W. Loosen et al., (2020), is a visual
representation of primarily numerical data (but
not only numerical) designed to improve the
cognitive processing of information by
consumers.
Scientists from all over the world actively
research visualization in journalism. E. Burdina
considers abstract thinking to be the key to
visualization, stressing that it precedes analysis,
and therefore, thanks to visual objects,
information is absorbed faster (Burdina, 2016).
V. Shevchenko (2014) offers a classification of
visualization forms, which is a continuation of
the opinion of S. McMillan (2006). Among the
visualization studies in media practice, we should
highlight the work of F. Tandoc and
O. Soo-Kwang (2017) examine the content of
The Guardian media resource. K. Medvedeva
(2020), Yu. Nagorna and N. Poplavska (2022)
consider methods of visualizing television and
print content using the example of local and
national mass media. M. Knight (2015),
analyzing news content, claims that journalists
often use infographics and maps for
visualization. P. Boczkowski (2004),
S. McMillan (2006), A. Rudchenko (2017), and
M. Engebretsen (2006) are supporters of
interactive visualization and consider it a unique
aspect of online communication and an essential
component of digital journalism, as they see it the
potential for active user involvement. At the
same time, other researchers analyzing media
practice followed the trend of decreasing
interactivity (Appelgren, 2017; Stalph, 2017;
Young et al., 2018; Domingo, 2008; Burmester
et al., 2010; Ojo & Heravi, 2018; Tandoc &
Soo-Kwang, 2017).
Despite a large number of studies on information
visualization in general, the visualization of
objects in data journalism is devoted to a small
number of scientific works. The visualization
studies in the data journalism system presented in
the scientific media discourse relate to analyzing
the winners and prize-winners of the Data
Journalism Awards. Such intelligence shows that
winners will likely use static graphics, maps, and
images (Loosen et al., 2020; Ojo & y Heravi,
2018). F. Stalph (2017) suggests that bar charts,
line graphs, and maps are appropriate for daily
news, but award-winning journalism differs from
daily news with interactivity and animation.
A. Córdoba-Cabús and M. García-Borrego
(2020), analyzing the finalists and winners of the
Data Journalism Awards 2019, found that the
most popular visualization method among the
