These features work together to create a powerful, user-friendly system for project planning. The interface is designed for simplicity and speed, allowing you to focus on your project rather than formatting.
Understanding the Gantt Chart Builder Interface
The Gantt Chart Builder interface is split into two main sections, as shown in the provided images. The top section displays the Timeline Properties and the Task Data table. The bottom section, Image 2, shows the Live Preview of the Gantt chart. This layout ensures a seamless workflow, where you define your project data in the top panel and immediately see the results in the bottom panel.

The Timeline Properties section at the top allows you to set the overall parameters for your project timeline. You can define the Start Date and End Date to frame your project. The Time Unit dropdown lets you choose the scale of your timeline, such as days, weeks, months, or years. The Step field controls the interval of the selected unit (e.g., every 1 week, every 2 months). The Column Width slider lets you adjust the visual size of each time unit, ensuring the chart is readable and fits your needs.
Below the timeline settings is the Task Data table. This is where you input the core information for your project. Each row represents a task. You can enter the Task Title, assign a Developer (using an avatar), and set the Start and End dates. The Progress field allows you to track how much of a task is complete, which is visually represented in the chart.
How the Live Preview Works
The Live Preview section is the heart of the Gantt Chart Builder. It dynamically updates to reflect every change you make in the Task Data table. As you enter a task, its bar appears on the timeline. As you update a task’s start or end date, the bar adjusts in real-time. This immediate feedback is crucial for understanding the impact of your changes.

The preview displays a clear, horizontal bar chart. The vertical axis lists all your tasks, and the horizontal axis shows the timeline. Each task is represented by a colored bar. The length of the bar corresponds to the task’s duration, and the shaded portion of the bar reflects its progress percentage. For example, a task with 80% progress will have 80% of its bar filled. This visual representation makes it easy to see the project’s overall flow, identify potential bottlenecks, and communicate the schedule to stakeholders.
Core Workflows: From Planning to Tracking
The Gantt Chart Builder supports several core workflows to manage a project from start to finish.
Creating a Project Plan
To create a new project plan, start by clicking the Add Task button in the Task Data table. Fill in the task title, assign a developer, and set the start and end dates. As you add tasks, the Live Preview will automatically generate a timeline. Use the Timeline Properties to adjust the chart’s scale and scope. Once complete, save your project locally as a JSON file and export the chart as an image for presentations.
Tracking Project Progress
To track progress on an existing project, use the Import JSON button to load your saved project data. Then, go to the Task Data table and update the Progress percentage for each task. The Live Preview will instantly reflect these changes, showing you the updated status of your project. This is a powerful way to generate a current status report.
Customizing Your Chart
Customization is key to making your Gantt chart effective. Use the Timeline Properties to tailor the chart to your project’s needs. If your project spans several years, switch the Time Unit to “Year.” For a detailed sprint plan, use “Week.” Adjust the Step to control the level of detail. The Column Width slider can help you fit more information on the screen or create a more concise overview.
