        "One of the [plotly](/plotly) particularities is that it offers two different ways to create plots: `plotly.graph_objects` and `plotly.express`. Both of them are high-level interfaces to plotly, but they have different syntaxes and functionalities. You can learn more about [here](/520-the-two-plotly-apis).\n",
        "\n",
        "- Plotly express has a **simpler syntax** and is more user-friendly\n",
        "- Plotly graph objects, on the other side offer **more flexibility** and customization\n",
        "\n",
        "In this post, we will see how to **use both** for [treemaps](/treemap). Let's start by load them (use `pip install plotly` if you don't have it yet):\n"
