Modern Dark Themed Interactive Dashboard

Design a modern, dark themed interactive dashboard UI featuring a collapsible sidebar with an upload field for file management and a set of tool icons for quick access to functions like settings and notifications. The main workspace should display interactive charts, graphs, and data visualizations using Chart.js or D3.js, with a dark background to ensure the visualizations stand out. The design should include smooth animations for the sidebar’s collapse and expansion, and interactive features such as hover effects, clickable legends, and real time data updates. The overall look should be sleek and minimalist, with clean typography and vivid colors for clarity and ease of use.
