Table 1 A description of EviAtlas functionality

From: EviAtlas: a tool for visualising evidence synthesis databases

Function Description Purpose
Landing page Background information about EviAtlas and systematic maps is provided, along with a ‘how to’ guide. Users can learn about evidence synthesis and find references and links to useful guidance material Learning more about evidence synthesis and visualisations
Data upload Users can learn about the style of systematic map data by examining the sample data or upload their own dataset for producing interactive and static visualisations Testing and learning, and production of bespoke, static and interactive visualisations for users’ own evidence syntheses
Evidence atlas Users can examine the data spatially on a cartographic map based on latitude and longitude data provided, clustering points to various degrees, colouring points by data attributes, and customising what information is displayed in pop-ups, including hyperlinks if present Producing evidence atlases (cartographic maps of evidence across a systematic review or map)
Map database Displays the map database as uploaded with customisable visualisation of columns. Users can filter numerical and categorical variables. Users can apply this filtering to the rest of EviAtlas to subset the other visualisations produced across the tool Examining data and producing easily readable databases of evidence
Descriptive plots Produces histograms for specified variables, displaying the number of study lines per level of the variable. For example, by year, or by country Producing histograms and other visualisations of trends across the database, as well as providing customisable template code for users learning the R programming language
Heat map Cross tabulates two variables to display the number of study lines across all levels of each variable Producing heat maps that help to identify knowledge gaps and clusters across the database
