Synthesizable in Remotion · key components of the agent-economy-launch template.

AgentChatBubble

Text bubbles appear and disappear around a central element, simulating a conversational interface. They feature subtle scaling, opacity changes, and a soft shadow.

+ Code construction recipe

Use `spring()` for position and scale animations for a bouncy, natural feel. `interpolate()` for opacity. Implement a `radial-gradient` for the central orb's color shifts and `box-shadow` for bubble depth.

DynamicFinancialCard

A digital credit card graphic displays a changing balance and agent name. Transaction bubbles animate in, showing deductions and updating the card's balance.

+ Code construction recipe

Utilize `Sequence` and `Series` for orchestrating the card's appearance and subsequent transaction animations. `interpolate()` for number counting animations on the card balance. Position and opacity animations for transaction bubbles.

GrowthGraphUI

A clean UI window displays an API endpoint, a price setter, and a dynamic line graph showing earnings growth with scrolling transaction details below.

+ Code construction recipe

SVG path animation for the line graph using `interpolatePath()` or manual `d` attribute interpolation. `spring()` for UI element entry. `Sequence` for step-by-step UI reveals and data updates. Text counting animation for earnings.
