Documents (vertices/edges) mutate within their lifespan (both in their individual attributes/values and in their relations with each other). 3. Past states of documents are as important as their present, necessitating retention and queryability of their change history.

The platform integrates enterprise data sources with our powerful graph visualization, layout, and analysis technology to solve big data problems. Tom Sawyer Perspectives enables developers to quickly develop production-quality data-oriented visualization applications. Two graphic modules—the Designer and Previewer—are used to build applications to visualize and analyze the specific data that drives each project. Using the Designer, developers extract or define schema, data sources, bindings, rules, views, filters, and searches. Additionally, they can also use the Designer to specify custom toolbars, tooltips, context menus, and graphical viewing and editing behaviors. -

Understand
SciTools
Understand is a comprehensive static-analysis and code-comprehension platform that helps software engineers “see” and understand large, complex code bases, whether legacy, safety-critical, or modern multi-language projects. It parses your source code and builds a complete “code dictionary” of every entity (files, classes, functions, variables), populating cross-references, call trees, dependency graphs, control-flow diagrams, and more. Through interactive, customizable graphs and visualizations, call graphs, control flow graphs, dependency trees, and UML-style class diagrams, you can explore exactly how parts of the code connect, which modules depend on which, and where changes may ripple across the project. Understand also computes detailed metrics at various levels (file, class, function) such as cyclomatic complexity, lines of code, comment-to-code ratio, coupling/cohesion, and other maintainability indicators; these metrics can be viewed in treemaps, exported to HTML or CSV.Starting Price: $100 per month -

CharityBase
CharityBase
CharityBase is a free, open source database and GraphQL API that aggregates fragmented data from the Charity Commission, Companies House, 360 Giving, charity websites, the ONS, and social media into a single, cleaned, normalized, and searchable dataset. It powers a public search portal where users can discover detailed profiles of UK charities, complete with finance, governance, and activity data, and offers a single GraphQL endpoint that responds in structured JSON with custom queries for counts, aggregates, and detailed lists. Designed to eliminate the heavy lifting of data collection and cleaning, CharityBase enables startups, grantmakers, and researchers to build digital tools, such as dashboards, reports, and grant-finding applications, without managing their own data pipeline. Its API supports both GET and POST requests, variable-driven queries, pagination, and live interactive playgrounds for rapid prototyping, all underpinned by regularly updated, audit-trail-backed records.Starting Price: Free -

JSON
JSON
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.Starting Price: Free
