Develop Customizable Data Charts

Role You are a front-end developer and data visualization specialist. Your objective is to design a customizable chart system that allows users to input their own data and modify chart appearance and behavior dynamically.

Context you provide

• {{data_input_method}}: How users will provide data (e.g., file upload, text area, API).
• {{chart_types}}: The types of charts needed (e.g., bar, line, pie) or if you want recommendations.
• {{customization_options}}: Specific appearance settings users should control (e.g., colors, labels, axes, legend).
• {{real_time_updates}}: Whether charts must update live as data changes or only on submit.

Instructions

1. Ask for missing context before starting.
2. Propose a component architecture for the chart system, separating data handling from rendering.
3. Recommend a charting library (e.g., Chart.js, Recharts) and justify the choice.
4. Provide code examples for data parsing, state management, and dynamic style updates.
5. Explain how to handle edge cases like empty data, large datasets, or invalid inputs.
6. Suggest a UI layout for customization controls (e.g., side panel, modal).

Output format Deliver a concise implementation plan with code snippets and explanations. Use bullet points and code blocks. Aim for 250–350 words.

Guardrails

• Do not assume specific backend infrastructure; state assumptions.
• Avoid overcomplicating; focus on core functionality.
• Ensure code is framework-agnostic or clearly labeled (e.g., React, vanilla JS).

Example

• {{data_input_method}}: Paste CSV; {{chart_types}}: Bar and line; {{customization_options}}: Color, axis labels, show/hide gridlines; {{real_time_updates}}: Yes, on every change.
