What is a relationship chart?

A relationship chart (also called a relationship diagram, character map, or character chart) is a visual that shows how multiple people, characters, or groups are connected to each other. Each person is drawn as a node, and the lines between them represent relationships such as friendship, family, romance, rivalry, or workplace hierarchy. Optional labels and arrows describe the nature and direction of each relationship.

If you need to see several kinds of connections across characters, factions, or family branches at once, use the dedicated relationship map maker. This page remains the general-purpose chart maker; the map guide focuses on reading a larger network as a whole.

What makes relationship charts so powerful is that they let you take in dozens of connections at a single glance. The same information explained in paragraphs would take pages of text and would still be hard to follow. With a chart, the entire structure of a story, a family, or a team becomes visible at once — making it obvious who the central figures are, where the conflicts sit, and which characters bridge different groups.

Beyond visualization, building a relationship chart is a thinking tool. The act of laying out characters forces you to surface assumptions, spot missing links, and notice imbalances. Writers often build a chart during the outlining stage of a novel for exactly this reason: contradictions in the plot become visible long before they reach the page.

What people use this relationship chart maker for

Relationship charts often get pigeonholed as "just for anime fans" or "just for novelists", but the actual use cases are much broader. Below are four of the most common ways people use this free relationship chart maker, with concrete examples for each one.

1. Tracking characters in dramas, movies, and TV shows

Long-running shows with sprawling casts — think prestige dramas, Korean series, fantasy epics, anime — can be exhausting to follow when you take a break and come back weeks later. Building a quick relationship chart of who's allied with whom, who's in love with whom, and who is secretly working against whom lets you re-enter the story without scrubbing through episodes. Many viewers also use these charts as a jumping-off point for fan blogs, recaps, and review videos.

2. Planning novels, comics, and original stories

For writers, a relationship chart sits right next to the character bible as an essential planning tool. Because relationships shift over the course of a story, many writers actually build three charts — one for the beginning, middle, and end — so they can verify that every shift in alliance, betrayal, or romance is properly set up. This is invaluable for catching plot holes before you commit them to a draft. The same workflow applies to webcomics, screenplays, fanfiction, TTRPG (D&D) campaigns, and original character (OC) lineups.

3. Mapping teams, projects, and stakeholders at work

When you join a new team or step into a new project, the hardest part isn't the work — it's figuring out who matters, who reports to whom, and who actually has decision-making power. A relationship chart can capture an org structure, a cross-functional project team, or a network of clients and partners in a single image that's far more useful than a static slide. Consultants, account managers, recruiters, and product managers all use this kind of chart to onboard themselves quickly and to brief teammates.

4. Studying history, mythology, and the social sciences

History students wrestling with "who married whom in the Tudor dynasty" or "how did Caesar, Pompey, and Crassus actually relate" find it much easier to remember those relationships when they draw them out instead of memorizing them from a textbook. The same applies to mythology, literature courses, social science research, and even genealogy projects where you want to map your own family tree across several generations.

OC relationship charts and fandom use

One of the most common reasons people search for a free relationship chart maker is to organize their original characters (OCs) or to map out the connections between characters in their favorite fandom. This tool is specifically designed to make those use cases easy.

• OC character lineups — Group your original characters by world, faction, or storyline, then connect them with relationships like family, partners, mentors, or enemies.
• Ship charts and CP maps — Visualize romantic pairings, rivalries, and "love triangles" in a way that's easy to share on social media or in your fandom server.
• Fanfiction planning — Build a chart of canon characters plus any OCs you're introducing, so readers can follow along without getting lost.
• TTRPG party trees — Map your D&D party, the NPCs they care about, and the factions they're tangled up with.
• VTuber and creator collab webs — Track which streamers or creators have collaborated with whom, perfect for fan-run wikis and explainer threads.

Build relationship charts on your phone — no app required

This relationship chart maker works fully on smartphones and tablets. Open Safari, Chrome, Edge, or Firefox, navigate to the page, and you can start building immediately — no app store, no install, no account. Every interaction (adding people, drawing lines, editing labels, dragging things around) is optimized for touch, so the tool feels just as natural with a finger as it does with a mouse.

This makes it perfect for capturing ideas on the go: jot down a quick character map on the train, sketch out a project's stakeholder web during a meeting, or brainstorm a fanfiction lineup from bed. Autosave keeps your chart in the same browser on the same device. To move an editable copy to another device, create a share link and open it there. Changes to those copies do not automatically sync. iPads and Android tablets work great too — many users prefer them for longer charts because the bigger screen makes complex layouts easier to read.
