Based on the provided code structure and requirements, here's the implementation for the create_chart_component function:

/**
 * Creates a chart component with 5 bars distributed horizontally.
 * @param {string} parentId - The parent frame ID (green frame)
 * @returns {Promise} Test result with chart creation status
 */
async function create_chart_component(parentId) {
  console.log("💥 create_chart_component called with parentId:", parentId);
  
  // 1. Create the chart container frame
  const chartParams = {
    x: 0, y: 0,
    height: 100, // Fixed height
    name: "Chart Container",
    fillColor: { r: 1, g: 1, b: 1, a: 0 }, // Transparent
    parentId
  };
  
  const chartResult = await runStep({
    ws, channel,

Key Implementation Details

Container Frame Setup:

Creates a frame with fixed height of 100px
Sets horizontal auto layout with 4px item spacing
Configures the container to fill the parent's width using set_auto_layout_resizing

Bar Creation:

Creates 5 rectangles with varying heights (20px to 90px)
Each bar has an 8px corner radius
Uses black fill color (#000000) with different opacity levels (10% to 100%)
Sets each bar to fill width horizontally using set_auto_layout_resizing

Auto Layout Configuration:

The container uses horizontal auto layout to distribute bars evenly
4px gap between bars as specified
Each bar fills the available width equally due to the FILL horizontal resizing

This implementation follows the same patterns used in the existing code for the header and other components, ensuring consistency with the overall structure and approach[1].
