    "\n",
    "ROOT can be seen as a collection of building blocks for various activities, such as:\n",
    "- **Data analysis: histograms, graphs, functions**\n",
    "- **High-level analysis interfaces**: RDataFrame\n",
    "- **Statistical tools** (RooFit/RooStats): rich modeling and statistical inference\n",
    "- **I/O**: storage of any C++ object, **column-wise** storage of datasets\n",
    "- **Math**: non-trivial functions (e.g. Erf, Bessel), optimised math functions\n",
    "- **C++ interpretation**: full language compliance\n",
    "- **Multivariate analysis** (TMVA): e.g. Boosted decision trees, Neural Nets\n",
    "- **Advanced graphics** (2D, 3D, event display)\n",
    "- And more: HTTP servering,  JavaScript visualisation"
