2A library for creating SVG files or just drawings that can be displayed in
3Jupyter notebooks

5Example:
6```
7 import drawsvg as draw
8
9 d = draw.Drawing(200, 100, origin='center')
10
11 # Draw an irregular polygon
12 d.append(draw.Lines(-80, 45,
13 70, 49,
14 95, -49,
15 -90, -40,
16 close=False,
17 fill='#eeee00',
18 stroke='black'))
19
20 # Draw a rectangle
21 r = draw.Rectangle(-80, -50, 40, 50, fill='#1248ff')
22 r.append_title("Our first rectangle") # Add a tooltip
23 d.append(r)
24
25 # Draw a circle
26 d.append(draw.Circle(-40, 10, 30,
27 fill='red', stroke_width=2, stroke='black'))
28
29 # Draw an arbitrary path (a triangle in this case)
30 p = draw.Path(stroke_width=2, stroke='lime', fill='black', fill_opacity=0.2)
31 p.M(-10, -20) # Start path at point (-10, -20)
32 p.C(30, 10, 30, -50, 70, -20) # Draw a curve to (70, -20)
33 d.append(p)
34
35 # Draw text
36 d.append(draw.Text('Basic text', 8, -10, -35, fill='blue')) # 8pt text at (-10, -35)
37 d.append(draw.Text('Path text', 8, path=p, text_anchor='start', line_height=1))
38 d.append(draw.Text(['Multi-line', 'text'], 8, path=p, text_anchor='end', center=True))
39
40 # Draw multiple circular arcs
41 d.append(draw.ArcLine(60, 20, 20, 60, 270,
42 stroke='red', stroke_width=5, fill='red', fill_opacity=0.2))
43 d.append(draw.Arc(60, 20, 20, 60, 270, cw=False,
44 stroke='green', stroke_width=3, fill='none'))
45 d.append(draw.Arc(60, 20, 20, 270, 60, cw=True,
46 stroke='blue', stroke_width=1, fill='black', fill_opacity=0.3))
47
48 # Draw arrows
49 arrow = draw.Marker(-0.1, -0.51, 0.9, 0.5, scale=4, orient='auto')
50 arrow.append(draw.Lines(-0.1, 0.5, -0.1, -0.5, 0.9, 0, fill='red', close=True))
51 p = draw.Path(stroke='red', stroke_width=2, fill='none',
52 marker_end=arrow) # Add an arrow to the end of a path
53 p.M(20, 40).L(20, 27).L(0, 20) # Chain multiple path commands
54 d.append(p)
55 d.append(draw.Line(30, 20, 0, 10,
56 stroke='red', stroke_width=2, fill='none',
57 marker_end=arrow)) # Add an arrow to the end of a line
58
59 d.set_pixel_scale(2) # Set number of pixels per geometry unit
60 #d.set_render_size(400, 200) # Alternative to set_pixel_scale
61 d.save_svg('example.svg')
62 d.save_png('example.png')
63
64 # Display in Jupyter notebook
65 d.rasterize() # Display as PNG
66 d # Display as SVG
