Particles

D3Blocks.particles(text: str, radius: int = 3, collision: float = 0.05, fontsize: int = 180, spacing: int = 8, cmap: str = 'Turbo', color_background: str = '#000000', title: str = 'Particles - D3blocks', filepath: str = 'particles.html', figsize=[900, 200], showfig: bool = True, notebook: bool = False, save_button: bool = False, return_html: bool = False, overwrite: bool = True)

Particles block.

The particles plot is to turn any word into an interactive visualization. With a mouse-move or touch, the particle bounce and then return to their original place. Various properties can be changed such as the bouncing, particle size, and colors. The original javascript is forked from Ian Johnson’s Block.

Parameters:

  • text (str) – String to be visualized

  • radius (float, optional (default: 3)) – Size of the particles.

  • collision (float, optional (default: 0.1)) – Response of the interaction. Higher means that more collisions are prevented.

  • fontsize (int, optional (default: 250)) – Text fontsize. When increasing: also increase width and slighly the spacing.

  • spacing (int, optional (default: 10)) – The number of particles that fit in the text. A larger spacing reults in less particles. A smaller spacing reults in more particles.

  • cmap (str, optional (default: 'Set2')) –

    Color schemes can be found at the references.

    • ’Turbo’, ‘Rainbow’, ‘Blues’, ‘Reds’, ‘Inferno’, ‘Magma’

  • color_background (str, optional (default: '#000000')) – Background color.

  • title (str, optional (default: None)) – Title of the figure.

  • filepath (str, optional (default: user temp directory)) –

    File path to save the output.

    • Temporarily path: ‘d3blocks.html’

    • Relative path: ‘./d3blocks.html’

    • Absolute path: ‘c://temp//d3blocks.html’

    • None: Return HTML content.

  • figsize (tuple, optional (default: (800, 600))) – Size of the figure in the browser, [width, height].

  • showfig (bool, optional (default: True)) – Open the window to show the particles.

  • notebook (bool, optional) –

    • True: Use IPython to show chart in notebooks.

    • False: Do not use IPython.

  • save_button (bool, (default: True)) –

    • True: Save button is shown in the HTML to save the image in svg.

    • False: No save button is shown in the HTML.

  • return_html (bool, (default: False)) –

    • True: Return html

    • False: Nothing is returned

  • overwrite (bool, optional (default: True)) –

    • True: Overwrite the output html in the destination directory.

    • False: Do not overwrite

Return type:

None.
