| 83 | +We exclude urban accessibilities, as it lacks the time cut attributes. We further processed the data as follow: |
| 84 | + |
| 85 | +``` |
| 86 | +key_data = Array(6) ["employment", "supermarket", "school_primary", "school_secondary", "gp", "hospitals"] |
| 87 | +minutes = Array(8) [15, 30, 45, 60, 75, 90, 105, 120] |
| 88 | +``` |
| 89 | + |
| 90 | +The `pct` in the variable denotes percentage of the dataset normalised to the global data in the UK. We filter the data to only use columns with percentage values, and exclude the raw data. This might be changed in the future depending on the visualisation requirements. |
| 91 | + |
| 92 | +The final data is combined with LSOA boundaries. |
