<https://s.mj.run/AW9G7jiV7Bg> Create an illustration of a stylized stock market trend chart. The chart should have a simple and clean design, featuring a fictional upward and downward trend with smooth curves and peaks. Use a horizontal time-axis at the bottom and a vertical price-axis on the left side. Add subtle grid lines to enhance readability. Color the trend line in a distinct, bold color against a light background to highlight the movement. Include some decorative elements like arrows or small circles to indicate significant points on the chart. Remember, this is a conceptual illustration, so focus on aesthetics and clarity rather than actual data accuracy. flat 2D colours, children book style, VECTOR, SANRIO STYLE --niji 6 --ar 16:9
