Absolutely feasible! Draw.io (now known as Diagrams.net) has all the tools you need to build clean, professional audio/sound frequency charts just like your example. Here's a step-by-step guide to make it happen:

• Open Draw.io and start with a blank diagram.
• Head to File > Page Setup to tweak the canvas size—landscape orientation works best for most wide frequency charts, but adjust based on your example’s dimensions.

• Grab straight lines from the Basic Shapes library to create your horizontal (frequency) and vertical (amplitude) axes.
• Use the text tool (the "T" icon) to add axis labels (e.g., Frequency (Hz), Amplitude (dB)). Bold them and pick a clean, readable font like Arial for clarity.
• Add tick marks by drawing short lines along each axis, then use Ctrl+D to duplicate them and space them evenly. Label each tick with the corresponding values to match your example’s scale.

• For smooth, natural-looking curves, use the Bezier Curve tool from the Advanced shapes library. Click to place anchor points at key peaks and valleys, then drag the control handles to refine the curve’s shape until it matches your reference.
• If your example uses stepped segments (like a discrete frequency response), use the basic line tool to connect short, straight segments end-to-end.
• Select your curve and use the right-side Style panel to adjust line thickness, color, or add subtle effects like a glow—just like your example might have.

• Use circles or squares from Basic Shapes to mark critical points (e.g., peak frequency, -3dB cutoff). Resize them and pick a contrasting fill color to make them stand out.
• Add text boxes to label these points (e.g., 12kHz Peak Response) and align them perfectly using the Format > Align tools.
• For shaded range highlights (common in frequency charts), drag a rectangle from Basic Shapes, set its fill to a semi-transparent color, then right-click > Arrange > Send to Back so it sits behind your curve and axes.

• Use the alignment tools to ensure all elements (axis ticks, markers, text) are perfectly lined up for a professional look.
• Tweak the color scheme via View > Theme to match your example, or customize colors manually in the Style panel.
• Export your finished chart through File > Export As—PNG, SVG, or PDF are all great options depending on how you’ll use it.
